Hi there! I understand that after you make a payment on the Checkers Sixty60 app on your iPhone (iOS 18.7), the screen goes blank, and you mentioned that you have pop-ups disabled. I'd like to help you get this sorted out.

First, just to clarify:
- When you say the screen goes blank after payment, does it stay completely white or black, or does it just freeze?
- Are you connected to Wi-Fi or mobile data when this happens?
- Have you tried restarting the app or your phone since this started?
- And when you mention pop-ups, is this the iOS popup blocker setting, or did you disable pop-ups somewhere inside the app?

This info will help me guide you better. Meanwhile, here are some initial steps you can try, as pop-ups are often needed to confirm payment or complete transactions:

1. Enable Pop-ups Temporarily:
Since you have pop-ups disabled, the app might not be able to show the confirmation screens after your payment is processed. On iOS, pop-ups normally come from Safari or within the app. Try turning pop-ups back on for the Checkers Sixty60 app and see if that resolves the issue.

2. Force Close and Re-open the App:
Double-click the home button or swipe up from the bottom and pause (depending on your iPhone model) to bring up the app switcher, then swipe the Sixty60 app off the screen. Reopen it and try again.

3. Clear App Cache via Reinstall:
Unfortunately, iOS doesn't give a direct cache clear option, but deleting the app and reinstalling fresh resets temporary data that may be causing issues.

4. Check for App Updates:
Ensure your Checkers Sixty60 app is updated to the latest version via the App Store.

5. Network Check:
Try switching between Wi-Fi and mobile data to rule out connection issues.

If after trying these you still get a blank screen after payment, let me know. At that point, we can check for deeper app or account issues or if the payment confirmation URL is being blocked due to the pop-up setting.

Does that all make sense so far? Let me know what you've tried and the answers to my questions. We'll get your app working smoothly again!
