No online features - EA account is restricted

Hi, everyone.

Everytime that I try to go online in Command and Conquer Remastered, I receive this message saying that my EA account is restricted from accessing any online features, as seen in the attachment.

Already went through all EA Support procedures given by EA Help staff, with no luck until now. From 24 games in my EA library, this is the only one that is blocking me from playing online. No account bans (ever!), Windows 11 PC completely updated , as the drivers, no issues with my EA account regarding any other game, game uninstalled/reinstalled, as well the EA App.

Any further help? Any suggestion would be appreciated.
