Thanks for taking the time to write in, and for your patience! While our team attempts to reproduce this issue, I’m curious if this behavior changes for you based on an artist.
For example, if you have a particular artist within your local library, can you add that artist to a playlist and see the tracks properly added?
Need to figure out, how “Tags” works. I thought I can “tag” some specific songs within a playlist, so that i can easily filter them out…(i have a lot of songs saved for my child and need to separate them)…but it’s not the way how it works.
