YouTube 4k video

Thanks for that information, KW1212. Since this issue seems to be limited the YouTube app, here’s some information provided by YouTube for help with their product:  Troubleshoot video errors, buffering, and freezing - Computer - YouTube Help. After assuring that your internet speed is enough, Select "iPhone & iPad" for more steps.

All the best.

Hello KW1212.

Thank you for using Apple Support Communities. If you're using the official YouTube app and it isn't properly working, you might want to follow these specific steps here: If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open - Apple Support

1.) Close and reopen the app

2.) Restart your iPad

3.) Check for app updates and install pending updates on your iPad: Update your iPhone, iPad, or iPod touch - Apple Support

To see if updates are available for the app, open the App Store, tap your profile icon, then scroll down to see if updates are available.

4.) Delete the app, then redownload it

When you do this, you might lose data that was stored in the app. Then redownload the app. Then check to see if the problem with the app is fixed.

If these steps don't help with the YouTube app, you might want to consider reaching out to YouTube for assistance with their app. Just in case, this link can show you how to reach them: How to contact an app developer - Apple Support

We hope this information is helpful. Thank you for using Apple Support Communities. Cheers

Hi KW1212,

Thanks for the additional information. Does it allow you to change the resolution for the video specifically? If so, does the video only play properly at 1080p? Are you able to view the resolution the video was recorded in?

Best regards
