Add to Up Next missing in iTunes 12.5.1.21
I have recently updated iTunes to version 12.5.1.21 in order to update my iPhone.
Now I do not have "Add to Up Next" in the context menu when I right click on a song or an album. I only have "Play Next" which puts the song or album at the top of the Up Next list instead of at the end. I used "Add to Up Next" to create a playlist each day for the evening. I don't want to create a permanent playlist because the next day I want to create a different list.
Has "Add to Up Next" been removed, or is there something wrong with my installation?
