[Web Player][Playlists] failed to save playlist changes

[otomebear]

I'm currently using the web browser on firefox and for the past couple of days, I've been unable to edit anything about my current playlists (descriptions, titles, cover art). At one point I couldn't add songs to the playlists, but that has since been fixed.

I can make changes on android through the app, but for some reason I cannot do it on the web browser

The error message I get each time is "Failed to save playlist changes. Please try again."

I've cleared my cache and restarted my computer, but otherwise I cannot find a way to solve this issue.

Anyone know how to help?
