This feature was initially announced by Google for YouTube users on iOS in June.
However, it rolled out for users in the US as a debut.
This feature was also available to Android users but was only accessible by users who had a premium subscription.
Users can also reposition the window as they like as they can move the mini-player by dragging it.
YouTube also lets users resize the mini-player by pinching with two fingers.
The Picture-in-Picture mode is only limited to users who have availed of the premium subscription.
This feature is available for only a limited period as well.
If the feature isnt available, users might have to reinstall the YouTube utility.
Users should have the latest YouTube version installed to jump into the new Picture-in-Picture mode.
According to the company, the premium testing for PiP ends on October 31.
