Unable to Access FC Ultimate Team Due to EA Account Connection Issue

Since Sunday, I haven’t been able to access FC Ultimate Team because I can no longer connect with my EA account. The issue happens in the following way:

When I start the game, a loading symbol appears for one to two seconds and then disappears without anything happening. After that, I’m brought to the main menu, where I’m clearly not connected to my EA account.

If I try to start Ultimate Team from there, the loading symbol just keeps spinning indefinitely. It would literally load for hours without anything ever happening. There’s no error message, no crash – just endless loading as it tries to connect to my account, but it never actually does.

I’d like to know if there is any solution to this problem, because I haven’t been able to access Ultimate Team at all since this started.
