When I try to play the “R&B” style radio, PlexAmp just shows me a spinning circle, or returns to the previous screen. Other style radios seem to work.
I have my library set up to use my genres, so the only way to play a style radio is from the artist page. I can however, play the “R&B” genre radio. From the artist page, I can select the style “R&B” and I see I have well over 100 artists associated with that style.
This happens on the Windows and Android version.
