Hello,
It seems that deleting a user from the PlayFab admin panel does not unlink the Facebook account (and maybe others accounts).
It is then impossible to link the Facebok account again because its ID seems to be kept somewhere in the PlayFab server.
Here is the steps I made to have the bug :
- Link a PlayFab account with a Facebook account.
- Delete the PlayFab account without unlinking Facebook.
- Try to link another PlayFab account with the same Facebook account.
- This should give a LinkedAccountAlreadyClaimed error.
- Try to do the same with forceLink=true.
- This should give a Error 500 HTTP error.
