I have a Firebase project shared by over 30 Android apps. Every app has its own OAuth 2.0 client used for Google Login.
Now I hit the 30 apps per one project limit: https://firebase.google.com/support/faq/#app-per-project
The firebase support is unable to increase this limit.
Now my question is:
Is it possible to use one OAuth client for multiple Android apps? All these apps are signed with the same signing key (meaning that they all need the same SHA-1 fingerprint). They all have different app ids of course.
