April 2020 now, and the problem of playlist description edits not being saved persists, but seemingly improved because I'm finding it an intermittent problem. Sometimes the changes I make to a playlists description ARE saved, and sometimes not. Earlier posts about this problem didn't mention it being intermittent, so I guess this is an improvement.
It seems like time is involved, leaving a playlist open for a while after revising its description seems to help make the changes stick. Also playing a track in that playlist seems also to increase chances of success.
I haven't tried the dowload the playlist and then undownload it trick, but it sounds promising.
Still, these are all annoying and kludgy workarounds for a problem that should be fixed and still isn't, at least not entirely.
It's particularly annoying because the description field usually contains specific details and reminders that are put there so they won't be lost or forgotten. It's like if the ink you used to fill in your dayplanner faded and disappeared. Very frustrating!
Maybe you guys should be fixing bugs and introducing new features if you want increased sales and retention. This is a pretty basic bug to fix, but it's clear this company this doesn't care and more reasons to not spend money on this product.
This is not a solution, because the problem is about the apps. However, I would say that those upthread could confirm that the changes they're making are taking place by checking in the browser player. I found this thread because I'm having the same problem (while simultaneously cross-checking with mobile, and finding that the changes exist and then disappear nearly immediately after appearing there) and just had the thought to use the web player to check them out. The most recent versions of the three playlist descriptions I changed did appear! Two of the playlists are new playlists I created just today, and one is a playlist I have been using since November 2016.
Thanks so much for reporting your own issues with playlist descriptions/images (really the UPDATE of an existing playlist) not working and often reverting. I was able to update an image yesterday after 3 times trying to update, and what I think might be happening is that the update is just SUPER delayed so it looks like it's not getting updated, but if you were to check back the next day the description would be changed.
Definitely still a frustrating bug that should be fixed by Spotify devs because otherwise, it looks like any changes you made to an existing playlist were not updated. Please submit a bug ticket for this and have a developer look into it.
Let me know if anyone else has seen this be the case.
okay so i logged into a different account on a web browser (not the app) and i check my playlists, most of the covers have updated for me but it just doesn't seem to work in the actual application lol its so frustrating
