Seems so simple, I'm embarrassed to ask

Good point.

I can only speak for myself as a Roon customer. I just now opened the Roon control app on my Dell laptop, iPhone, and iPad. They are all three where I left them. Dell is sorted by Most played, iPhone is sorted by Date added, and iPad is sorted by artist. I use a Nucleus that runs 24/7 if that makes any difference.

Over and out.

interestingly enough…

on my iPhone, where it’s never remembered my preference of sort-by-date-added and always reverts back to sort-by-artist, IT REMEMBERED MY PREFERENCE FROM YESTERDAY.

Further updates as events warrant.
