My wife and I (who use iPhones 6 Plus and 7 Plus with iOs 10.3 and 10.3.1, respectively) recently noticed that when we try to sort playlists we have created (whether it be by "Recenlty Added," "Artist," Title," etc), after leaving or force quitting Spotify or entering antoher playlist and returning to the playlist in the question, the playlist has resorted back to whatever the previous sort method was used on the playlist. Basically new sorts in IOS aren't saving. I've tried replicating this on my macbook air and I find that the Spotify desktop application appears to remember/save the new way I sort my playlists, but it doesn't appear to then update/replicate in the IOS versions. Has anyone else encountered this issue and know a fix for this?
