I am using Unity 5.5.3, PlayFab SDK 2.23.17061 and Google Play Game for Unity 0.9.39a and am having the following issues for Title ID 9686:
1. When attempting to use LoginWithGoogleAccount after successfully authenticating with Google and receiving a valid Server Auth Token, PlayFab returns 409: Conflict. There are no other client calls being made at the time.
2. When attempting to use LinkGoogleAccount after successfully authenticating with Google and receiving a valid Server Auth Token, PlayFab returns success. However, the UserAccountInfo.UserGoogleInfo is filled in correctly, but the PlayerProfile.LinkedAccounts does not contain the Google Play account. The linked account doesn't show up in the Game Manager either.
I can also successfully un-link and re-link the Google Account, but it never shows up in the PlayerProfile.LinkedAccounts colleciton.
The user I have been testing with is PlayerId: B0BE0926C12F514E
Any thoughts?
