Hey! I understand you're having trouble with the Vita Mahjong app getting stuck after an ad plays and not going back to the game, right? That can interrupt your gameplay for sure.

To get us started, can you tell me if this happens every time you watch an ad, or just sometimes? Also, have you tried closing and reopening the app after this happens?

Meanwhile, here are some steps we can try:

1. Force close the app: Since you're on an iPhone with iOS 18.6.2, swipe up from the bottom of the screen and pause in the middle to open the app switcher, then swipe the Vita Mahjong app off the screen to fully close it. Then reopen the app and check if it resumes properly.

2. Restart your iPhone: Hold down the side button and either volume button until the power off slider appears. Power off, wait 30 seconds, and power it back on. This can clear temporary glitches.

3. Check your internet connection: Ads require a good connection; a weak or spotty network can cause the app to hang. Try switching between Wi-Fi and cellular to test.

4. Clear cache (if possible in the app): Some apps have a setting to clear cache or temporary files, which might help if the stored ad data is corrupted. If you don't find such an option, the next step might help.

5. Update or reinstall the app: Make sure Vita Mahjong is updated to the latest version from the App Store. If it already is, try uninstalling and reinstalling the app (be sure your game progress is saved to your account or cloud to avoid losing it).

6. Disable Ads (if you want ad-free): Check if there is an in-app purchase to remove ads, which eliminates the issue entirely.

If you've already tried these or the problem persists, let me know so I can step up the troubleshooting or escalate if required.

Are you okay trying these steps right now?
