Hello,

Thank you for providing the additional details and screenshots. It seems like you're experiencing a consistent issue with the real-time preview on the iOS app. Here are a few steps you can try to resolve this:

1. Update the App: Ensure that you have the latest version of the Ultralytics iOS app installed. Updates often include bug fixes and improvements.

2. Check Model Compatibility: Make sure your model is compatible with the app. The app supports YOLO models optimized with FP16 or INT8 quantization.

3. Device Performance: The iPad 9th generation should handle the app well, but ensure no other heavy applications are running simultaneously.

4. Reinstall the App: Sometimes, reinstalling the app can resolve unexpected issues.

If the problem persists, please let us know if there are any specific error messages or logs. This will help us diagnose the issue more effectively.

We appreciate your patience and are here to help! 😊

Hello,

Thanks for the update! It’s great to hear that it worked on your Pixel 7 using Google Chrome. 🎉

For the issue on your iPad with Safari, here are a few suggestions:

1. Clear Cache: Try clearing the cache and cookies in Safari. Sometimes, old data can cause unexpected behavior.

2. Safari Settings: Ensure that JavaScript is enabled in Safari settings, as it's essential for the app to function correctly.

3. Try Another Browser: If possible, try using a different browser on your iPad, like Chrome or Firefox, to see if the issue persists.

4. Update Safari: Make sure Safari is updated to the latest version available for your iOS.

If the issue continues, please let us know. Your feedback is valuable, and we're here to help ensure a smooth experience across all devices. 😊

Thank you for your patience and support!
