I have the same issue in the last 3 days. When I go to the overview page I get a Roon icon spinning
and it is stuck there. All other (genre, Album, tracks are working).
So I go in Settings and disconnect from Tidal and reconnect (going back to Tidal site login) After doing this Tidal is working and the Overview page in Roon.
I have done these steps at least 2 to 3 times in the last 36 hours.
Could you please try updating to the newest build of Roon (build 538) which was released today and verify if you’re still seeing the same behavior afterwards?
