Game Center and App transfer

We transferred application, using guide there: https://developer.apple.com/help/app-store-connect/transfer-an-app/overview-of-app-transfer/

We use Game Center to identify users via playerid https://developer.apple.com/documentation/gamekit/gkplayer/1521127-playerid

After transferring application playerid for our current users is changed, and so users are unable to login

How can we restore playerid for our users? For "Sign in with Apple" there are migration process, so there are no issues, is there something like that for Game Center?

Hello, have you found any solution to the problem?

I have the same issue. Did you figure anything out?
