The short answer
The Canvas Parent app only flags work as "missing" when a teacher sets it up that way, and its alerts are widely reported to fire inconsistently. So overdue assignments can sit there with no label and no notification — until they've already dented a grade.
None of that means you're using it wrong. It means the app was built to display data, not to reliably catch what needs your attention tonight. Below are the four real reasons things slip through, the manual way to check today, and a calmer alternative.
Why the Canvas Parent app misses missing assignments
1. "Missing" depends entirely on the teacher
Canvas only labels an assignment missing when three things are true: the teacher set a due date, that date has passed, and the assignment is configured to accept online submissions. Plenty of real classwork doesn't meet all three — paper handouts logged later, no due date entered, "practice" that isn't submission-tracked. That work is still overdue in real life, but Canvas never gives it the missing label, so it never shows up on a missing list.
2. The app's alerts fire inconsistently
This is the complaint parents report most: you switch on missing-assignment alerts, and they simply don't arrive — so you end up opening every class, one at a time, to check by hand. The Canvas Parent app is a capable viewer, but as a watchdog it's best-effort, and best-effort is exactly what fails on the busy weeknight you needed it.
3. Alerts and observer settings are easy to misconfigure
Missing-assignment alerts have to be turned on per student, and whether you see full assignment detail also depends on how your district set up parent (observer) access. One toggle in the wrong place and the notifications you expected never had a chance.
4. Canvas isn't always the official gradebook
In many districts — including Orange County Public Schools (OCPS) — the official grades live in a separate system, and Canvas data can be delayed, hidden, or incomplete. So the Canvas Parent app can look "all clear" while the real picture is still forming elsewhere. Treat Canvas as an early-warning view, never the final word.
How to check for missing assignments in Canvas right now
Until you have something that watches for you, here's the honest manual routine:
- Turn on the alerts you do have. In the Canvas Parent app: menu → your student → Manage Student → Alerts → switch on Assignment missing (and low-score alerts if you want them). Repeat for each child.
- Open each course and read the assignment list. Look for items marked past-due, unsubmitted, or missing. The app groups by course, so this is one class at a time.
- Cross-check on the web. The Canvas website sometimes shows detail the app doesn't. Log in through your district's parent portal and review the same courses.
- Check your device notifications. Even with Canvas alerts on, your phone has to allow them. Confirm notifications are enabled for the app.
- Confirm with the teacher when it matters. Because "missing" depends on setup, the ground truth is still the teacher. When a grade is on the line, ask.
The real problem: checking is a chore, not a system
Notice what that routine actually is — a nightly manual sweep across six classes, on top of everything else a weeknight holds. You can absolutely do it. The trouble is that missing work doesn't wait for the nights you have energy to check, and the one night you skip is the night it matters. A found-tonight missing assignment is a ten-minute fix; the same one found in November is a grade already bent out of shape — and because a GPA averages across all four years of high school, that dent doesn't go away when the class does.
A calmer way: one reliable check, done for you
ByBedtime does the checking so you don't have to. You connect your existing parent Canvas access once — read-only, and never your school password — and it watches on a schedule. Instead of a nightly hunt, you get one calm evening brief, and an alert only when something actually changes: newly missing, due tomorrow, or finally turned in. Every brief shows when it last verified, so silence is never mistaken for "all clear" — the one thing an unreliable alert should never do.
| The nightly question | Canvas Parent app | ByBedtime |
|---|---|---|
| "Is anything newly missing?" | Open each class and compare against memory | An alert within the hour, deduplicated |
| "Did they turn it in?" | Keep re-checking until it changes | One "handled ✓" the moment it happens |
| "Am I seeing everything?" | Silence looks the same as fine | Every brief timestamps its last check |
| Alerts | Per-event, and often don't arrive | One calm brief a night + only real changes |
It's honest about its limits, too: ByBedtime is an early-warning layer, not the official gradebook, and it says so plainly. It's built to catch the missing assignment while it's still fixable — not to replace your school's system of record.

Common questions
Why doesn't the Canvas Parent app show missing assignments?
Canvas only labels an assignment "missing" when a teacher sets a due date, the due date has passed, and the assignment tracks online submissions. Many teachers don't set it up that way, so overdue work never gets the missing label. Missing-assignment alerts also have to be switched on per student, and parents widely report the app's alerts firing inconsistently — leaving you to open each class by hand.
How do I turn on missing assignment alerts in the Canvas Parent app?
Open the menu, choose your student, then Manage Student and Alerts. Turn on "Assignment missing" (and low-score or grade alerts if you want them). Alerts are set per student, so repeat for each child. Even with alerts on, delivery is best-effort and depends on your device's notification settings.
Why are my Canvas Parent app notifications not working?
Check three things: alerts are set per student (menu → your student → Manage Student → Alerts), your phone must allow notifications for the Canvas Parent app, and your observer account must be paired correctly with each child. Even configured perfectly, parents widely report Canvas Parent notifications arriving inconsistently — delivery is best-effort. If an alert can't afford to be missed, don't rely on a single push notification; use a nightly routine or a service that checks on a schedule.
Is there a more reliable way to know when my child has a missing assignment?
Yes. ByBedtime connects to your existing parent Canvas access read-only and checks on a schedule, then sends one calm nightly summary plus an alert only when something is newly missing, due tomorrow, or finally turned in. It never asks for your school password and always shows when it last verified, so silence is never mistaken for "all clear."
Does ByBedtime work with my school?
ByBedtime works with schools that use the Canvas learning platform and offer parent (observer) access. It's launching first for Orange County Public Schools (OCPS) families and expanding to other Canvas districts. It is an independent service, not affiliated with or endorsed by any district or platform.
