Likely causes
- Notification permission disabled for the app
- Sensitivity or motion zones set so the area is excluded
- Phone battery optimisation stopping background alerts
- Subscription feature expired or not enabled
- Firmware bug after an update
Quick checks
- Check the phone notification settings for the app
- Open motion zones and sensitivity in the app
- Confirm the doorbell is online in the app
- Check whether alerts arrive with the app open
Step-by-step fix
Review motion zones, sensitivity and alert schedule
Enable background refresh and disable battery optimisation for the app
Update the doorbell and app firmware
Test in front of the doorbell with the app closed
If alerts never fire, reset the device and re-add it to the account
