Push Notifications Suddenly Stopped Working – No FCM Tokens Generated, Tried Everything!

Integrations
Resolved

Hi everyone, I’m having an issue with push notifications in two apps. Up until last week, everything was working fine, and I haven’t made any changes related to notifications—I’ve just continued working on the app development. The other day, I decided to test the notifications again, and I noticed that not only am I no longer receiving them, but the FCM tokens aren’t being generated anymore either.
I’ve spent the last 4 days trying to fix this, following every guide and piece of advice I could find, but still no luck. Has anyone else encountered this issue recently?
Also, I should mention that the two apps were created under two different accounts, and now neither of them generates FCM tokens. I’ve even considered the possibility of an issue related to the Blaze Plan, but everything seems fine on that front.

It’s incredibly frustrating because I’ve had to dismantle both the app and the database piece by piece, even though I was at a good point with the project. I just can’t figure out how it suddenly stopped working on its own.

Any ideas on what could be happening or what else I could check?

What have you tried so far?
  • Regenerated the config files.

  • Validated the Firebase schema.

  • Re-deployed Firestore rules.

  • Deleted and re-deployed push notifications.

  • Checked the Cloud Functions region (europe-west3) to ensure they match across the board.

  • Reviewed the permissions to make sure f[email protected] has access, and that “cloud functions invoker” permissions are set to “all users.”

  • I even duplicated the project and recreated the Firestore database from scratch.

Still, nothing works, and I can’t figure out what’s causing the issue.
