I am running a dual boot laptop with Mint 18.1 XFCE and Windows 10. My phone is an iphone and I am a Spotify Premium subscriber. On Windows I can transfer local files to my phone and play them through Spotify no problem. When I try to do the same thing from Mint my phone is stuck on "Downloading...Waiting to download." I know the phone can communicate because I can play non-local files through the phone using the Linux client as a remote. Local files play fine through the Linux client itself, so I don't have the issue that most people seem to report. Any ideas? I change around local files frequently and I hate to keep having to boot over to Windows to make this work. I will probaby cross-post this on the Mint forum as well.
Any thoughts on this? I suppose I'd consider switching to Google Play. Same price and they seem to be able to handle this easily, and from what I can tell all the music I care about is available there as well.
