I have local files in my desktop Spotify. Every time I restore/change my phone I have to do a bunch of things to get them transferred to my iOS Spotify.
This particular time, Local files show as "Pending" in the desktop app, no activity is going on. In the iOS app, Local Files playist has no green arrow but all the files inside do have a green arrow next to them. If I try to play any track - Spotify pops up the Track view with "--" for time and no scrubber and nothing happens.
