YouTube rolling out 'incognito mode' for more users: Report
The "Turn on Incognito" button would be visible at the bottom of the account page and users would be properly notified when they go incognito through several indicators, visible at the top-right corner and a bar at the bottom of the app, saying "You`re incognito".
Although, to add a video on playlist, users would have to briefly turn the feature off, save and go back to the new mode.Image source : pixabay
