[SOLVED] Notifications not working in AAB build: Fetching the token failed: FIS_AUTH_ERROR. Code: E_REGISTRATION_FAILED.

Expo SDK
15

My API key in GCP is being called but a lot of 403 errors (explains the FIS_AUTH_ERROR I guess). When I check the metrics in GCP for the firebase installations api there are over 1000 requests for the createInstallation API method…

So the key is being called from my app (or somewhere) but it’s not going through.
