You can watch a video in a small window with the YouTube picture-in-picture (PiP) feature, which hovers on top of other open apps on your screen. This means that you can continue to use other apps, check your email, and browse the web as you continue to view movies. There could be several reasons why the YouTube picture in picture not working on your device. Verify whether Picture in Picture is enabled for YouTube, update the app to the most recent version, delete any data and cache from the YouTube app and then restart your device.
