why does it work on ue5 but not on ue4.27

Hello guys, who faced such a disaster - version UE4-27 does not want to work correctly with PLAY GAME SERVICES - everything is set up and when the game is activated on the phone, it does not log in and just throws it out of the game, and if everything happens on anriale UE5, then everything is correct. Who can tell or have any infa about this?
