I’m having the same issue since yesterday.
If you leave the app open, Roon is at the end updating these sections below “Genres for You” but sometimes is doing it after 30s, sometimes after 1 minute and very few times it’s as fast as the rest of the page.
I’m having the same issue also in the Artist page with all the contents below Collaborators loading also after 30-60s
I thought it’s related to some Roon server (maybe the one responsible for Valence) because anything else, be it local library, Tidal or Qobuz is loading very fast.
My set up is:
Mac mini M1
multiple devices via USB and Ethernet
40k tracks plus Tidal and Qobuz
