Not able to drag-and-drop / add songs to most of the playlists

[3JSA]

Brief description of the issue

For several version I have had a problem with the desktop version of the Spotify where when trying to drag and drop songs to playlists it is not possible. When I drag the song to the name of the list in the side the green + never shows up. The same happens if I right click on the song and then choose the option add to playlist.

This does not happen to all playlists but to like 80% of them.

I have found two workarounds which are: 1) play a song from the playlist you want to add to and then it is possible to add to it; 2) edit the playlist without changing anything and save and then it is possible to add to it.

To note that the same account works fine in other platforms such as on my phone.

Steps to reproduce the issue:

No idea what can be done to reproduce the problem.

What steps you’ve tried already:

I have tried several steps (not sure of the order): 1) log-out and in; 2) uninstall and reinstall spotify (with deleting of the library parts as well); and 3) delete the cache.
