In my case, only clue I have is that for some reason EA App doesn't show Steam as a connected account and that would be reason for this issue. When use browser and navigate to my account, the Steam is there. It is only App where it is not showing.
I also can't do the re-linking because I recently did the link and there is 6 month time period where I can't do the link again. Contacted EA support about this and they say that they can do nothing. So my only hope is that somehow this issue disappears or I wait 6 months to see if re-linking would help. The support person even copy-pasted sort of explanation that they can do nothing and immediately closed the chat 😀
This is really horrible customer service for poor products....
