Hello. Unfortunately this is not the crux of my problem. I did discover, as you did, that when I purchase something from Qobuz and download it, the file ends up on the hard drive of the computer it is downloaded on, not the Antipodes Server. So I have to copy them over. And sometimes they are not immediately visible in My Music, but I just give it time.
My problem seems (to me) a little stranger and occurs when I try to use the Qobuz app from within the Antipodes App selection. The app opens normally and gives me options to play my music, search, play the favorites I identified in Qobuz via my web browser etc. Sometimes I want to play something I don’t own by streaming it via Qobuz. This is where I run into problems. Normally this works well - I can search for just about anything in the Qobuz ecosystem and play it through my K50. But a few weeks ago this stopped. I can still search/select songs/albums and see them added into my queue, but they won’t play. The other apps (e.g. Radio Paradise) work just fine.
It is very frustrating, but I really appreciate everyone trying to help me troubleshoot.
