What is a YouTube picture in picture and why it is not working on my device?

[louisegrant]

YouTube picture-in-picture (PiP) is a feature that allows you to watch a YouTube video in a small window that floats on top of other apps on your screen. This means you can keep watching videos while checking your email, browsing the web, or using other apps. If this YouTube picture in picture not working on your device, then there could be multiple reasons behind it. Check if Picture in Picture is enabled for YouTube, update the YouTube app to the latest version, clear the YouTube app cache and data and restart your device.
