I noticed that in one of the 2 devices in which I'm testing an app did not received the firebase messages, but both used to work fine, one day it stop receiving them. I read the tutorial again and googled this error but did not found anything that worked, I went back to an apk that I knew for sure was working but it didn't work either.

I ended up clearing the app data in the android os settings, which is equivalent I believe to delete it and install it again, and it fixed the issue, I now can receive firebase messages again.

What could be causing this issue? Something related with the token, maybe it did not refreshed itself?
