Stream YouTube video in Full HD resolution on iOS Safari I have an iPhone X and an iPad Pro, both running iOS 11. I notice, when streaming a YouTube video in iOS Safari, the video resolution is limited to a maximum of 720p.

For e.g., when watching this video on Safari on macOS, I am able to stream it in the maximum available resolution i.e. 1080p. But in Safari on iOS, the output is limited to a maximum of 720p.

Is this behaviour configurable in YouTube settings or Safari? I notice, the same video can be played back at full resolution in the Videos app in iOS, when downloading it on a Mac and transferring it on iOS device.

I do not wish to use the YouTube app for iOS.
Safari on iOS is restricted from playing videos at Full HD resolution. To view them at higher resolution, using the YouTube app is your only resort.
