My progress is missing

Check your network connection and restart the app. If the nickname on the Account screen is different, you may be connected to a different anonymous account.

Watch the ad to completion, return to the app, and wait briefly. Rewards cannot be granted for canceled ads or ads that the server cannot verify. Repeated taps do not grant duplicate rewards.

I want to delete my account and data
