The problem may be the use of the word "Online" in "Online games". They use it to describe turn based games where each side has one day plus to make a move.
Yes, all the other games are "online" but they are not the day plus correspondence games.
Try playing some of those.
hi, i just tried registering for December 1st 1000/1200 tournament and it said i havent played 5 online games. I have played more than 5 on the chess app but not off the website. does it matter?
