If coins or an item are missing, fully close and reopen Stompers first.
If they still do not appear, contact support with your username, what you expected to receive, when it happened, and any screenshots or receipts. Support can review coin and item issues, but App Store payment refunds still go through Apple.
Items appear periodically. If there are no items nearby, new items should spawn after about 2 hours.
You may be too far away from an item to pick it up.
If you have no power-ups, use the Get item button from the home screen.
The helmet icon means your Stomper is wearing the helmet.
Power-ups depend on the item, timing, and what is happening in the challenge when you use it.
If a power-up looked wrong, send support your username, your friend's username, the item used, and a screenshot or screen recording of the result.
Try updating Stompers, fully closing the app, and reopening it.
If the error keeps showing, send support your device model, iOS version, Stompers app version, and a screenshot of the error.

If you opened this page from the app, your user ID, device, OS, and app version are included automatically. Otherwise, send your username and screenshots if the issue is account-specific.
