All of a sudden the Music stops playing when phone screen goes black .Videos that were download ,are now not . Songs are in & out of download . I have tried every possible fix myself & tech support from Utube & Tmobile. Still no fix on the black screen pause. And Im having to rework all the video songs to regular if available . Such a waste of time on 1 app . And I pay for premium. How I miss Goggle music . Would be interested in moving all of my music to another app.
