Hi there.
I am trying to use LinkGoogleAccount to link a Google Play Games account to the user's PlayFab account (logined by AndroidDeviceID already).
Attached codes include login with android device ID and linking in current project, and now I am in trouble in dealing with two errors.
1. already linked error
After first request in an the LinkGoogleAccount(), error message says that google account I choose to link is already linked.
- There is only one player in the Players in "Players" of the game manager.
- There was few players in past, but I deleted all the player excepts one. (yesterday)
(Is this error related to dummay account left?) - Left only one player is now linked with android device only.
- Is it necessary to unlink already linked android device before linking google account?
like an image of below link says?
(https://api.playfab.com/docs/tutorials/landing-players/account-linking)
2. Google API error code: invalid grant details: already redeemed
I get an API error code when I try to set forceLink to true at second request of LinkGoogleAccount().
- As far as I know, PlayGamesPlatform.Instance.GetServerAuthCode() is for one time usage, so should I sign out before sending second request? or is there any way to get refreshed serverauthcode?
I'm not sure I described my problem correctly.
Please let me know if any additional information is required.
Thanks.
P.S. Is there any sample projects for beginner like Unicorn Battle project posted in last year? I cannot find recent sample projects excepts (https://api.playfab.com/docs/tutorials/landing-players/sign-in-with-google).
