'Firebase subscribe to topics not working after reinstalling app
I made an app which was working fine until I found that after deleting and reinstalling the app it doesn't receive messages anymore that are sent to a a topic, although it does receive a message that is sent to the id-token of the app. Does anybody know what might be the problem? Firebase or my app?
Update: After clearing cache and data of the app it can receive notifications again. If reinstalled there's a chance of not working. I have to do some more testing, but I think it is solved by setting android:allowBackup="false" in the app manifest.

After the uninstall and reinstall, your app on that device was assigned a new device token. According to that documentation:
The registration token may change when:
- The app deletes Instance ID
- The app is restored on a new device
- The user uninstalls/reinstall the app
- The user clears app data.
That new token won't have all the same subscriptions that the old one had. You'll have to re-subscribe to the topics that the user was interested in on that device.
It's not just reinstalls - your app should be ready to handle new tokens at any time, based on the criteria listed above. The linked documentation illustrates how to listen to token changes.
