Can’t login into my EA FC 25 Ultimate Team

Hi so I’m trying to go on ultimate teams for EA FC 25 but I keep getting this message: Please not that you can only play Football Ultimate Team on one device at a time. Your UT session on this system has been closed, as you are already playing on a newer generation system. But the problem is that I’m not playing on any other system. I only have my PlayStation 4 and that’s the only thing I have to play the game, so it shouldn’t be saying that I’m on a different system. This is very frustrating and I don’t understand why it won’t let me login on my game.
