Firebase working in Unity editor but not in Android build

[Achille Pace]

Hello,

I'm trying to make a mobile game using a realtime database to store some scores.

In Unity editor, everything works. On our last IOS build (which was around 2 weeks ago, it worked), but it doesn't do anything at all on our latest Android build.

I searched on internet and I saw someone who did Assets/ExternalDependencyManager/AndroidResolver/Forceresolve.

I did it too and it ends on 

"Resolution failed

Failed to fetch the following dependencies:
com.google.firebase:firebase-app-unity:+
com.google.firebase:firebase-auth-unity:+
com.google.firebase:firebase-database-unity:+ "

I installed firebase at least two months ago without the package manager, on Unity 2020.3.31f1

Did someone have this problem before ?

I fixed but I'm pretty sure it's just a band-aid fix

I basically installed the Firebase Database again, without even uninstalling what I already had, and somehow it works :')
