Did you published your game in Play Store if so and you enabled Google's apk signing then the sha1 certificate would have been changed so in this case you have open your project in Google cloud platform (Google APIs)and copy the new signature by Google from play console section and paste it in Google APIs and save your project and wait for few minutes. This should work. ;)
yeah i did all that yesterday.
-----------------------------------------------------------------------------
but i have a question: in Google cloud platform (Google APIs)below the Credentials there is the OAuth consent screen i clicked on that it says
Verification Status
Needs verification
Because you updated the application logo, your app registration requires verification by Google. Please prepare your app to submit for verification.
i need an Authorized domains, Application Homepage link, Application Privacy Policy link.
I dont have an Authorized domain, but i have a website made with wix.
