I don’t receive notifications from my apps anymore

Verify first in Settings -> notifications -> App settings, that all toggles are checked.

iodéOS uses microG services: an open-source & privacy-friendly re-implementation of the Google Play Services. The ‘Google Cloud Messaging’ (GCM) push notification service, used by many apps & allowing them to send notifications to you, is activated by default. If you don’t receive these types of notifications it probably means that GCM was accidently unactivated. To reactivate it:

  1. Go to Settings -> System -> microG -> Google device registration -> uncheck and check again ‘Register device’.
  2. Go to Cloud Messaging -> uncheck and check again ‘Receive push notifications’.

You should now be receiving notifications from your apps.
