I am using Unity to make an Android app that is integrated with PlayFab. The latest version of the Google Play SDK for Unity (version 0.11.01) is always returning the error code GoogleOAuthNoIdTokenIncludedInResponse when calling LoginWithGoogleAccount. The release notes say it integrates Play Games Services v2 SDK so the authentication flow has changed dramatically. But when I get an auth token from Google with PlayGamesPlatform.Instance.RequestServerSideAccess() and validate it is correct, PlayFab returns the previously mentioned error message.
I downgraded the Google Play SDK in Unity to Version 0.10.14 and I was able to successfully log in with LoginWithGoogleAccount on the PlayFab side which leads me to believe all account configurations on the Google and Playfab sides are correct.
