My folder structure seems to have been corrupted. I'm hoping that it's possible to restore this structure to an arbitrary earlier point in time (Say, Feb 7, 2015)
Symptom 1: My folder organization structure has recently become inconsistent between devices. (Perhaps the result of using various platforms and devices to add new playlists and write to that structure?) The structure appears correctly in the OSX app/client, but problems appeared on iOS8: a chunk of folders suddenly appeared at the wrong level, in a folder that was previously deleted but somehow persists (It's called "Bibio").
I had been using this three-leveled folder structure: Folder (26 of them) for each letter of alphabet > Artist > Album Playlist. This allows for speedier navigation, especially my WDTV box. Recently, some of these alphabet folders got moved arbitrarily to this other folder (the evil "Bibio" folder), and I can't get the 26 lettered folders moved back to the "root" level where they belong, no matter how I move them. (The fact that they didn't land where the interface told me I was dropping them compounded the problem). This is actually the second time in the last two years I've had this exact problem, which seems to appear once I've added a great many playlists. My solution the first time was to delete everything, maybe a thousand playlists - which is not the preferable remedy from my standpoint as a Premium subscriber.
Then I began to remove the lettered folders to try to get all playlists at the root level, creating a real hash. Still the persistent Bibio folder on my Phone. It always appears as the last available folder, though there should be others at the same level after it. The Bibio folder does NOT appear in the OSX client, where the structure had appeared correctly.
Symptom 2: Folders don't land where I drop them. They've begun to land a few folders above the place that is highlighted, even at a different level of the heirarchy. According to a post by Spotify's "David" this was the result of some residual playlist code in the index, and was fixed by "pushing some buttons" on the other side of the curtain.
How do I get my "buttons pushed," too?
