@Scott_Harrison Since July 17, when I use Google Sign-In, the account selection popup stopped showing all of my Google accounts except just a few. This issue also affects many other users trying to sign in with Google. Before July 17, I could see all of my accounts in the popup, and there was not any problem - so there is no a problem in setting Google Cloud Console. Also, the plugin stopped providing the accessToken (now I only receive the idToken) after sign in using googleSignIn.signIn(googleListener)
I thought I caused the problem, so I build the source code of my previous app version from before July 17 - and I observed the same problem. But once I installed an artifact build on July 16 from the same version of the source code, it works as expected. Then, I removed all of my external plugins to ensure they don’t conflict with the googleSignIn plugin. The issue still persists. That’s how I came to a conclusion that there might’ve been an update of the plugin that started causing such behaviour of not showing all users and not getting the accessToken.
