Game keeps disconnecting and sending me to main screen - PC

The game consistently disconnects since launch. Every action I take on Ultimate Team is basically a dice roll. Can't even do SBCs properly or even manage my Squad. At every request there's a very high chance that the game will bug out saying there was some issue with servers and it will either send me back to the main screen or stay in a bugged state until I go to the main screen and reenter Ultimate Team. This is not interminent, it's been happening consistently since the game launched. It's incredibly annoying.

Who the hell do I talk to in order to get this issue under investigation? I see multiple people complaining about this on Reddit, Steam and here in these forums but there's no information anywhere confirming the issue. It's been weeks now, is anyone at EA even aware that this is happening? I'm pretty sure this will likely * with my first WL this weekend.

I'm based in Sweden if that's relevant, playing on PC, cabled. I do not give away games, I do not play for long sessions, I never did anything on the market or got any kind of ban for anything. I'm an average user that just wants to play the game. No problems on any other games, it's only EAFC and only on Ultimate Team. A friend in Denmark plays the game on Xbox and he says that there are no issues there. I tried everything on the official technical troubleshooting pages, and there it says my connection should be perfect. Can anybody help?
