The ‘quality’ option you see when watching videos in the YouTube mobile app now shows Auto, Higher Picture Quality, and Data Saver presets.
I’ve often found myself accidentally burning through my daily mobile data quota after watching a few high-resolution YouTube videos, oblivious of the fact I wasn’t hooked to a Wi-Fi network, but cellular data. Yes, the app has offered an option to restrict video quality to sub-HD resolutions when using mobile data, but it is not easily accessible. That is finally getting solved with what appears to be a server-side update for the YouTube mobile app that adds new video quality controls.
