Original:
I am currently talking to an EA Support rep as am I also have the issue getting the message "Missing Online Access" when loading up ME:A and am being told that all Online Features for the game have been Shut Down.
Not just Multiplayer, but the abilitiy to Import and Export characters and World Save States etc.
I thought these features were still available but am being told different.
Don't know when this happened or if it's even correct, it's just what I'm being told.
EDIT:
So after speaking with the Representative some more, it seems they were able to restore access to the Online Features for me. It took them a couple tries with me logging out and relogging into the game and EA App each time to see if any of the soltions worked.
After a couple tried I logged out and back in and the game finally connected me back Online. The Rep said they had to find a solution in an post from 2018 although they didn't say which, and I think it may have been an internal Fix post for Support Members.
The fact of the matter is the problem can be fixed, although it will take going through a Support Rep as we ourselves cannot do anything to fix it and it must be done through EA's end.
