I will try and explain this; let's say you've chosen an album to play, and it's playing right now. when you look at the Playing Next list you can see the upcoming songs. If I choose another album that I want to play after the current one is finished, I select Play Later - but this is where the problem is. The new album gets inserted right after the currently playing song, not after the whole album. That seems more like Play Next, not Play Later. For everyone who's posts I've read on this topic, it seems they are having the same issue. Also, I don't know what version of Apple Music you have, but mine does not offer a "Play Last" as you mention in your reply. I've been using iTunes/Apple Music since it was first offered years ago, I am not a novice that needs instructions on how to operate it. I believe this is a bug that needs to be addressed by the programmers/designers of the product. Play Later should put the music you've chosen at the End of whatever list of music you already have playing.
