Quobuz playlist not working, individual playback spotty

I just purchased Audirvana and the remote app, and signed up for the trial Quobuz service.

So far, not so good. When I do get a song to play, it sounds great. I created a Quobuz playlist and, while I can get individual songs to play with some futzing around, when I select Play the entire Playlist, nothing ever happens.

Currently, I’m streaming everything from my MAC Mini, and I’ve used a Yamaha WXC-50 and Pro-Ject Streambox DS Net as players, both having the same issue. Everything is on a wireless mesh network ysing TP-Link Deco M9+.

Does anyone have any suggestions? I really want to make this work!
