Hello fellow Spotify people
The problem is, a year ago I added some Local Files to one of my Playlists on my Macbook Pro. I then 'Downloaded' aka made Available Offline over the same WIFI connection to import the Local Files into the playlist on my iPhone. This worked fine.
Recently I have since deleted these Local Files from said Playlist, added new higher quality versions of the same songs, plus some additional New Local Files to the playlist, all songs have Album Artwork in iTunes.
On the Macbook Pro (OS Sierra 10.12.2) the replaced/additional Local Files all play fine in Spotify, Old Local Files have been deleted also, however the Album Artwork is not loading when song is playing. Furthermore, on the iPhone 7 Plus (iOS 10.2) the Old Local Files are still showing in their original place in the playlist (only blacked out as you obvs can't play them - even though 'Hide Unplayable Songs' is checked in iPhone Spotify settings)
On the iPhone I have 'Downloaded' the Playlist and the new songs have imported, except for 1 or 2, and it constantly sits on 'Waiting to download', presumably as it's still trying to find the Old Local Files which no longer exist on the Macbook Hard Drive. It's confusing as to why the iPhone playlist wouldn't just mirror the MacBook playlist. Again, Album Artwork does not load when playing New Local Files on the iPhone.
I have deleted the Cache, and tried a completed re-install on the MacBook including using an AppCleaner app to delete hidden files. The re-install seem to work for clearing the files on the MacBook playlist, however when you go to Download the playlist it just sits on 'Waiting' though on WIFI.. And yeah, the Album Art also doesn't load.. Also if I search 'com.spotify.Client' on 'This Mac' the cache file doesn't appear to exist, not sure if this has something to do with it?
I have also deleted all Devices in Spotify Account settings.
Since doing this, I have also replaced my iPhone, and restored my brand new phone, including downloading the Spotify app. Yet the Old Local Files remain in their old positions of the iPhone playlist. Could it be something trapped in iTunes backup of iPhone?
I really don't know what more to do, but I would love to have those old files cleared on the iPhone, for the playlist to completely Download on both Devices, and for all album artwork to show when playing.
Any leads would be greatly appreciated.
Many thanks.
