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

I finally managed to produce an error from getExpoPushTokenAsync()! I also installed Sentry but that’s not displaying it.

The error: Error: Fetching the token failed: FIS_AUTH_ERROR. I’ve done a quick search on the expo forums and I figured it could be that I’m doing something wrong regarding app signing or it’s a bug in Expo? Fetching the token Failed, message : FIS_AUTH_ERROR - Help: Expo SDK - Forums

My app signing/upload key and api key all match in terms of sha-1 etc. Can’t do anything there.

I’m not too sure what to do next. I’ll read up on this issue some more for now. Thanks!
