I'm not sure if I have the same issue, but last week I downloaded the game for my new Series X through ultimate pass. Before downloading the game I created an EA account and synced my Xbox to it and then downloaded the game. I played for two days, trying to get assist medals to cut down time rather than trying to get the unlock 6 strike teams achievement. But two days later I could not connect online.
I logged into EA account and discovered my account had been permanently banned. I appealed and they said I broke TOS but not exactly what I had done, they said the ban would stay but allowed me to re-appeal which I'm now waiting on the studio to investigate
I played about 6 or so games online, so not sure if someone sent a prank report on me to EA, or after looking around the net, others have said AI bots in control of new accounts are causing issues. But not sure as neither EA or anyone else seems to be able to clear this up. Cancelled my Ultimate Pass just in case they decide not to lift the ban, as the whole reason I bought the series X was to be able to play all those awesome backwards compatible games that EA have on the Series X and get all the achievements. Now though, all this has done is cause me to lose out, Microsoft to lose out as well as EA. I really hope they can sort this asap.
Good luck to the rest of you chaps having issues too.
