I'm still having problems with Apple Music downloads to my phone. I click make available offline and all is well. As soon as I leave the house / wifi signal the problems begin, songs are then listed as not available and greyed out. Strangely, when I come connect to wifi again they are available and not greyed out even though they didn't have a chance to be redownloaded - so the songs must hve been on the phone all along, just unavailable. I'm in an area with poor cellular signal and wondering if this is the issue, that the phone can't check tha my account is legit?
