Description

I'm experiencing insane downtime with my FCM implementation. I've been sending pushes to my users using tokens (~90%) and topics (10%).

All tokens generated with version 14.9.2 stopped working for me. I also confirmed this with other developers working on projects I'm not involved in, and they confirm the same issue. Tokens generated with this library don't work with any admin SDK (tested with Python and JS) and don't work from the Firebase Messaging admin panel when using the "Test message" button.

Updating the library to 15.1.1 solved the issue (newly generated tokens work), but we have ~100k users not receiving their pushes now, and that will require them to update the app.

Sending pushes using topics still works.

Reproducing the issue

Properly configure Firebase and FCM, and ensure version 14.9.2 is listed in your pubspec.yaml.
Print your FCM token and remember to accept push permissions.
Send the push using the "Send test message" button in the Firebase Messaging panel.
Push not received.
