The subject says it all. In the games (ATS and ETS2) the profiles seem to connect as usual. But via Browser there is only a message: "You need to be signed-in to access this page."
Edit: Login from phone worked. Opera's privacy mode, too (regular mode not). Firefox and Edge don't.
Edit #2: Login doesn't work at all if I don't keep the game running in the background. Strange, isn't it? Until yesterday everything worked fine.
Edit #3: Today (24th) everything seems back to normal. So, keep your fingers crossed!
