Dear @Jan Reeves,
Thank you for posting your question in the Microsoft Q&A forum. From what you’ve described I understand that you’re using Microsoft To-Do on iPhone, but notification reminders no longer appear despite reinstalls and restarts.
To better assistance, could you please confirm following information:
Are you signed into To Do with the same Microsoft account across all devices (iPhone/PC/Web)?
Do reminders appear on any other device (Windows, Mac, or Web at to‑do.office.com)?
- Do you also use a Smart Watch (notifications can route to Watch instead of iPhone)?
In the meantime, i recommend steps below:
1/ Sign out before reinstall
A simple reinstall does not clear account cache unless they sign out.
Open To Do > Settings > Sign out, then uninstall To Do, restart iPhone, reinstall, and sign in again.
2/ Refresh Background App Refresh
Settings > General > Background App Refresh > To Do, even if it appears ON, toggle it OFF > ON again.
This aligns with known causes in Microsoft To-Do iOS reliability issues.
3/ Force a push token refresh
Turn Airplane Mode ON, restart iPhone, then turn Airplane Mode OFF. This forces iOS to re‑register push tokens used for notifications.
4/ Verify the reminder itself
Edit a task > ensure Remind me has a future time/date and the task sits in a list that’s syncing.
