This question already has an answer here:
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.
