Sorry if you’ve already tried it, but did you restart the Innuos as well as your iPhone? Also it will help if you update the Sense app on your phone to the latest.
To use Sense … sense app > server > advanced settings > Roon > toggle to Off
Roon software bug with Innuous Zenith 3?
I'm still using Roon with my Zenith 3. Since the latest update (Roon 1.8 build 880) I'm having a strange problem. Every few days, Roon will show about 1/3 fewer albums than I actually have. Also, when this happens and I try to save a new album from Tidal or Qobuz, there's no artwork displayed and when I go to my albums>Sort by date added, the new album is not there. If I turn off and back on the power to the Zenith, all problems go away and the newly saved album appears as does the artwork . A few days later the same problems come back. Roon tech support is unresponsive. I know.... I could download the new Innuous software to substitute for Roon. But I'd still like to have Roon working correctly. Is anyone else experiencing these problems? Any ideas/suggestions would really be appreciated.
