For challenges hosted by others, there is no direct button to leave or unjoin a Challenge. However, if you don't check in your progress for 3 consecutive days, you will be automatically removed from the Challenge.

For challenges that you're the host, you can delete your challenge as an action to leave or unjoin.

No, once you log your progress for a Challenge, it cannot be edited. Make sure to enter the correct data during check-in.

No, you cannot log progress data for the past days. Once a day has passed, you cannot log progress for that day. Be sure to check in daily to keep your streak going.

If you are still receiving notifications for a Challenge that you have already deleted, try signing out of your account and then signing back in, or reinstalling the app. If the issue persists, please contact our support team for assistance.

As of now, the Challenge system is only available on the phone app. We are planning to release the Challenge system on other platforms in the near future. Stay tuned for updates!
