Anyone else used Apple Music streaming and had it continually fill up the free space on your phone? I thought I had a couple of gigs free, so was surprised to start getting free space warnings. Deleted some stuff and before long I was getting the warning again. Rebooted the phone and that seemed to clear the cache, so the space was unoccupied again. We'll see if it keeps happening. I don't have a 16gb phone, but it seems like this could be a problem for those that do, if it's a prevalent issue.
