I use YouTube a lot and often use the premium feature of having my phone locked when I'm listening but since the Beta update if I lock my phone it'll sometimes cause the PIP to freeze when I unlock but audio will still be playing and if I try to touch anything on the screen other than my notification panel or swiping up to use the home button. I have to restart the phone or wait for the app to close itself.
This also happens occasionally if I just leave the app open (not locking it with the PIP) too.
Thank you for your feedback. If you haven’t already, Please send us an error report from the Samsung member’s app -> Beta Feedback -> Error Reports to help us debug the issue. We apologize for the inconvenience and appreciate your contribution to the beta program.
