Up till about 2 months ago Apple Music was my music of choice app but after an update my music switches itself off and on at will?? I can be half way through a track and it will randomly stop then not play any of the following songs on my playlist. Soo frustrating when on sitting out and you have to keep looking at you phone all the time!! Totally backward in today's digital world.... What's happening Apple?? We pay enough for a premium music app so where is it??
