I have almost 5K songs in a number of playlists, and many weeks ago I set them all to download so i could listen to them offline during an overseas trip I am now on. I set the Storage setting to use my SD card. Everything was great. All of a sudden Spotify is telling me that it is downloading every song, and the Storage setting had been changed to internal storage. wth? When it first starting doing this about 30 minutes ago the "downloaded" indicator on all of my songs was green, indicating that the songs were downloaded, so I was mystified. Now all the playlists and songs say "waiting to download" and it's 18% along. Any ideas why this happened? My internet connection here is not strong enough to download 5K songs!
I'm on a Galaxy S8+ with the latest OS and version of Spotify.
