Popup player eg. (Twitch and YouTube) is not working as intended. So it's a feature that allows you to continue watching a current video while using other apps via a small popup window which you can move around your screen, however, when switching app, you can see the popup window form but then disappear to the bottom of the phone screen. It will then reappear for example when using the keyboard in another app. Interacting with the popup in anyway will make it disappear again to the same place. So this is not very usable right now.
