After updating to 2.773 the menu entry “Add to queue” works no longer. The function seems to work as usual (see screenshot) but the content of the selected playlist has not been added.
By the way the function “Clear and Play” works flawlessly.
Sorry to be such a bother, but experiencing this exact same problem. Unable to add playlists directly to the queue. Its current impossible to add multiple playlists to the queue. Would you please advise on a potential fix or upcoming update.
Please, please, and thank you ever so much.
