Problems connecting to Google Play Games API (Failed to sign in)
Hey,
I recently made an update for my game and included leaderboards and achievements using the Google Play extensions. The game was working fine and the new functionality was working correctly until yesterday at night, when it simply stopped working. Every time I open the game and it tries to connect to GPG it returns the error 'Failed to sign in. Please check your network connection and try again'. Now, I've double checked everything in my Google Play console, Google API Console and in the game. The SHA-1 and game credential all seem to be correct. I'm losing my mind as I intend the game to be functional by halloween and I invested some money in ads for the game on Facebook and Google Ads. I need assistance as quick as possible.
