Hi there! I understand you're experiencing an issue with purchasing energy in Tomb of the Mask, and the app is kicking you out. That sounds frustrating, but I'm here to help!

Let's start by checking a few things to see if we can resolve the issue:

1. Restart the App: Try force closing the app and then reopening it. To do this, swipe up from the bottom of the screen (or double-click the Home button) to open the app switcher, then swipe the Tomb of the Mask app off the screen to close it completely. After that, relaunch it.

2. Check for Updates: Ensure that your game and iOS are both updated to the latest version. In the App Store, go to the "Updates" tab and see if there's a new version available for Tomb of the Mask.

3. Free Up Storage: Sometimes, low storage can cause app issues. Go to Settings > General > iPhone Storage and check if you have enough free space available. If it's low, consider deleting some unnecessary apps or files.

4. Reinstall the App: If the above steps don’t work, uninstalling and reinstalling the app can sometimes resolve persistent issues. Just make sure your game progress is saved, as usually, it’s linked to your account.

5. Check Internet Connection: Ensure you have a stable internet connection, whether through Wi-Fi or mobile data, as this can impact in-app purchases.

6. Contacting Support: If the problem persists, please feel free to reach out to Tomb of the Mask support at [email protected] for further assistance.
