I can’t lock in my team when playing H2H MUT 24

I'm having the same problem, I've seen a couple threads. And so far not a single fix. I've been trying to play Friendly h2h for 2 days now and I can't lock my team in. As soon as I go to lock my team in or change my strategies are glitching out. Then I deleted and re-download the game. Then I reset all my data on my system. At this point if there no fix imma need a refund for my most recent purchases since I can't even use them, and haven't been able to the entire time. Only message I receive is "our server can't process this right now" and I get a kicked. Don't ask for any screen shots or anything else yall know what the problem is and if you don't check one of the many threads where yall attempted to no resolve.
