SO... music keeps being deleted off my iPhone 6 Plus . For example... I put the acid rap mixtape by chance the rapper on my phone yesterday morning.Then when I left work some tracks were missing. When I woke up this morning the rest of the album was gone. This happens at least once a week. It is not just with that album... It's with any song I add to my phone from my computer. I updated to the newest ios. iTunes match is not on Thoughts? Has this happened to anyone else?
