Hi! I understand that your Vita Solitaire app plays only one game, then shows an ad asking for an upgrade, and after that, it crashes and disappears. Let’s get that sorted out together.

First, just to clarify:
- Are you using the free version of Vita Solitaire or have you already purchased some upgrade?
- Did the crashing happen suddenly or after a specific update?
- Have you tried restarting your iPhone or reinstalling the app yet?
- Also, do you notice if the crash happens right after the ad plays?

For now, here’s a simple step-by-step approach to try:

1. Restart your iPhone: This clears temporary memory issues that can cause crashes. Just press and hold the side button and volume button, then slide to power off. Turn it back on after a minute.

2. Force close and reopen the app: Swipe up from the bottom to access the app switcher, find Vita Solitaire, swipe it off the screen, and then open it again.

3. Check for app updates: Go to the App Store, tap on your profile icon, and scroll to see if there’s an update for Vita Solitaire available. Install it if so.

4. Reinstall the app: If the problem persists, delete Vita Solitaire from your iPhone and reinstall it from the App Store. This can clear corrupted app data.

5. Check your internet connection: Ads sometimes cause issues if the connection is unstable. Try switching to a reliable Wi-Fi or turning on Airplane mode after the game to see if that stabilizes things.

If none of these steps fix the crashing issue after the ad, the problem might be a bug related to the upgrade prompt itself. In that case, contacting Vita Solitaire support through [email protected] would help. They can check for any known issues or send you a more specific fix.

Would you be comfortable starting with these steps? Also, please let me know what you’ve already tried so I can tailor the help better.
