Random play / Roon Radio bug?

An observation that might be of use…

When i play a set of tracks randomly and then allow Roon Radio to pull in music similar to what was played last in the queue, Roon Radio often fails to play continuously, i.e. to keep adding music to the queue. The music eventually just stops. It can happen in a few min or an hour or more. However, (!) it seems to play without interruption when i unclick “play randomly.”

hmmmmm

where exactly is this "play randomly"thing that you can click? can you post a screenshot?
