I have a premium account and I just started having this issue...
(I'm using the desktop version of Spotify on my MacBook Air)
I make a playlist, add songs and a cover if needed then set it to playlist. But, it doesn't show up on my profile and other people can't see it too. I tried this with my other account and I had the same problem too. I also tried setting the playlist public on my phone and it shows up there but not on my desktop version. What's going on and how can I solve this? I'm someone who loves making playlists for others so this is quite annoying 😞
Update: I tried doing it on the Web player and it worked but it still didn't show up on my desktop version.
