I am currently reworking an app that was created in 2017 which uses Google Sign-In for unity to let users sign in and get the users name and profile pic. The app also uses Firebase analytics and Crashlytics now.
I have been having some issues with Google Sign-In and while looking at it noticed that it has not been updated on GitHub for 3+ years.
I was wondering, should I stay with Google Sign-In or try moving to Firebase Auth. Am I completely misunderstanding the point of FirebaseAuth?
