Premium desktop application on Windows 10.
I updated to version 18.104.22.1688.g4b100958 using the blue-highlighted "restart & update" notification on the account/settings/log out dropdown menu.
After updating, I am unable to drag songs into playlists or playlists into folders.
Was having no issues prior to the update. Am willing to help debug if there's any helpful logs.
