I’ve asked you for a 24hr game via chess.com. THere should be a challenge to accept in your notifications and/or email.
The other option is either random games or joining another tournament from the upoming list. Probably best to choose one with a grading limit to keep things more even,
For example.
https://www.chess.com/tournament/obsessed-aficionados for players graded under 1500
If you click the join button you will get a notification from Chess.com once the tournament is full and it starts.
There seems to always be a big gaps as the games in each round finish. For example I am curently taking part in 16 tournaments but only have 13 active games.
