I have loved the YouTube app for years. I am even a Premium user. In the past few months, however, the app has been super buggy. If I shut my screen off, the video will stop after a few seconds. If I pull up a different app on my phone, same thing happens. It used to show me the YouTube banner with navigation controls (FF, pause, rewind, etc.) while I was using other apps. Now that doesn't show up. I'm excited for the app to be fixed, but for now it's a mess.
