Nova stuck on Roon input

Last night I played something via Roon.

This morning despite trying NAS sources and Qobuz via Chromecast built-in I was unable to play anything on the Nova which seemed to be stuck with the last played Roon audio artwork, even a quick power on/of and it came back in Roon mode.  Roon app had been quite by this point.  A longer power on/off cleared it, but not seen the issue before.

I downloaded the Roon trial a few weeks ago and it was flawless in operation initially, but after a software update for Roon on the Mac it does not seem as stable.
