I have used firebase authentication (Google login) in my app. It was working properly when i have not publish my app on play store, but when i published app on playstore. It’s not working.
I am facing the exact problem. I don’t know if it is my phone’s fault (Android 6).
If you uploaded the app in .abb format, try to upload it in .apk. My phone still can’t sign in, but in newer phones they can.
me too what is the problem
Not sure if you saw this thread, but this is the solution that worked for me. My app is published to the play store as well.
Guys, your apps are signed by Google and thereby won’t work, please search the community…
