Fix a missing reminder or alert
Check whether the issue is a local reminder or a message from another phone.
What to do
Check permissions and sound
Allow notifications and check silent mode, focus settings, and any app-specific restrictions.
For a reminder
Check the scheduled day, time, and app reminder setting. For a remote alert, check both devices’ connections and the linked recipient.
Verify with a controlled test
Agree on the time and recipient first. Use a backup contact method if the alert is important.
