Hello, I can't access Ultimate Team on EA SPORTS FC 26 on my PS5

If the Companion app works but your PS5 can't connect to Ultimate Team, it doesn't sound like an account ban. It could be a corrupted local profile, a network issue, or your club getting stuck on the console after the power outage. I'd try signing out of your EA account on the PS5, rebuilding the PS5 database, and testing with a different internet connection or mobile hotspot. If none of that works, you'll probably need to contact EA Support, as they may need to reset something on your account from their end.
