Describe the bug
When using Anonymous sign-in, a user that already signed in before is unable to sign in again and I'm getting
Identity+is+already+linked+to+another+user` instead.
To Reproduce
- enable anonymous sign in (for me its automatically anon signing in when not authenticated
- sign in with oAuth
- sign out
- sign in again
Expected behavior
The new anon user should be merged with the existing user
