Hi Codestics,
thanks for posting on the forum!
Could you confirm what versions of Unity and Authentication you are using with your project?
I assume you are getting this error when you load your application this comes out in the logcat?

Hi SebT thank you for the response

I am using unity 2022.2.1f1
Google Play Games plugin for Unity v11.01
This is coming out on my LogCat after running it on my Android device and connected to unity.

I connected all the services as were stated - I even uploaded the app for production with testers and added also a second key with sign in.
