Hi there! I understand you're having trouble joining tournaments in Mahjong Club. That can be confusing! Let's find out what might be going wrong.

Could you provide a little more detail? For instance:
- Are you seeing an error message when you try to join?
- Have you been able to join tournaments before, or is this your first attempt?
- Are you part of a specific club or tournament that you're trying to join?

Once I have a clearer picture, I can guide you through potential solutions!

Not in any tournament - coffee fan club - played 724 games

Thank you for providing that information! It looks like you're part of the Coffee Fan Club and have a solid amount of games played, which is great.

Since you're not currently in any tournament, let me check a few possibilities for why you might be unable to join tournaments. Here are a couple of things we can look into:

1. Account Status: Make sure your account is in good standing and hasn't received any temporary suspensions or issues.

2. Tournament Availability: Sometimes, tournaments may not be open for registration. Double-check that there are tournaments currently available to join.

3. App Update: Ensure that your Mahjong Club app is updated to the latest version. Sometimes bugs can occur in older versions that could affect tournament participation.

4. Connectivity Issues: Check your internet connection to ensure it's stable since a poor connection might hinder some of the app’s functionalities.

5. App Settings: Check if there are any specific settings within the app that might restrict tournament participation.

Could you let me know if you've checked any of these items or if you have more specifics that might help narrow down the issue? If the problem persists, we could consider contacting higher-level support.
