Only within the last 3 days the app has become relatively unusable on my S9+ with various earbuds (haven't bothered checking other devices yet). I am listening to music and browsing another app(various) when the music stops. I click back to Amazon Music and the display shows nothing but the play progress line/bar thingy, only across the center of the screen. I can click back from there to the menu (it doesn't lock up) but once I made sure it was up to date I opted to leave this review.
