Same here! What is going on!? I created the playlist about a month ago on the desktop app for PC's, but now when I try to make edits to the description it stays during my session, but if I close out of the program and go back in it is gone... Poof... 😐
It's been over six months since this thread was posted and the issue has yet to be solved. I have tried updating my playlist descriptions and pictures multiple times only to discover nothing has changed once I re-open the app. Clearing the cache doesn't help, and neither does re-installing the app. I shouldn't have to make a new playlist and copy everything just to be able to update the description/picture
I use version 22.214.171.1240.g1fcff12a (Mac OS High Sierra 10.13.3)
Same thing with me: I edit the playlist description and, as soon as I close the app, the new description is gone for good. It has been a while since this issue has been reported. I wonder if anyone is taking a look at it.
Using version 126.96.36.1990.g1fcff12a on Mac OS X El Capitan 10.11.6.
