So I have been playing on Xbox because I've been torn on using Steam or the EA app. I have Xbox's Game Pass Ultimate so I get a 10% discount or whatever.
I am using my stream PC and downloaded BF6/Redsec on it via Steam and EA. I have no issues launching the game on Xbox, or Steam, however, when launching the game from EA, I get the online restrictions or whatever.
It has to be a server side issue and they're likely working on it. If you want to start playing, download it via Steam and you'll sign into your EA account. Seems to work fine that way for me!
EDIT. Also wanted to note I have no penalties on my account
