Thank you both.
The main issue is that I HAVE deselected Autoplay within the songs that have Autoplay selected, but each time I go back in to those songs, Autoplay has turned itself back on.
My understanding is that if I turn it off and exit the song back to the playlist or select another song, then when I go back in to the song in which I turned AP off, it should still be off, no?
Because in my case AP has turned itself back on, and I don’t understand how or why - it’s never done this before, and it’s not turned on in the playlist setting.
Any ideas? Is it me, or a glitch somewhere?
