E/FirebaseInstanceId: Token retrieval failed: AUTHENTICATION_FAILED - what changed?



I'm not sure what's going on here, I pulled my recently updated repo and every time I open the app to debug it on an emulator I get E/FirebaseInstanceId: Token retrieval failed: AUTHENTICATION_FAILED as the app loads up the main screen. However this hadn't happened before today so I don't know what could've changed? I deleted the app from the Firebase console and re-added it (through Firebase Assistant), but that didn't fix it either? I've included my build.grade file but I'm not sure what else I need to be looking at, any assistance would be appreciated.

yes! I've been using a test account that was created months ago - what doesn't make sense is why this is happening before a user even logs in - I've noticed that sometimes the emulator's internet connection is spotty (which makes even less sense as I'm connected through LAN on my desktop) so I'm wondering if that's the issue.

My guess is that a new version of the Google Play library has been released and your test device/emulator need update his currently installed version.



Check the Google Play Store app on your device/emulator, make the update, and you should be good to go !
