Apple Music offline playlist keeps deleting
I have a playlist in Apple Music which I keep downloaded on my iPhone for offline listening. However at random times my iPhone just deletes the whole playlist or a few songs so then I can’t listen to them without an internet connection. This sometimes happens numerous times a day. I have optimise storage turned off in Music settings so I don’t know why it’s doing this. It’s really frustrating since I’m paying for the service and yet I can’t use it. This has been happening for the past 3-4 months, I’ve had Apple Music for the past year and this never happened before that.
