Hello! I understand you're having trouble with the Puzzle Page app crashing on your iPad version 16.7.11, and you want to know how to delete and reinstall the app while keeping all of your data. Let’s work through this together!

1. Backup Your Data: First, let’s ensure your data is backed up. If you have enabled iCloud backup, your game progress might be saved there. To check:
- Go to Settings.
- Tap on your name at the top to open Apple ID.
- Tap on iCloud and then iCloud Backup.
- Make sure iCloud Backup is turned on and tap Back Up Now to create a fresh backup.

2. Delete the App: Now, let’s delete the app:
- On your iPad, find the Puzzle Page icon on the Home Screen.
- Touch and hold the app icon until it jiggles.
- You will see an ‘X’ or a Remove App option (depending on your iOS version). Tap it and then confirm you want to delete the app.

3. Reinstall the App: Once the app is deleted, you can reinstall it:
- Open the App Store on your iPad.
- Tap on the Search tab and type in “Puzzle Page”.
- Find the app in the search results and tap the Download button to reinstall it.

4. Restore Your Data: After reinstalling, when you open the app, it should prompt you to restore your data if it was saved to iCloud. Follow those prompts to restore your progress.

If you are not seeing any options to restore your data, it might be necessary to check if the app itself supports cloud saves through an account or another method.

Let me know if you encounter any issues with these steps! Are you satisfied with the solution I provided?
