Master Volume on my iPhone goes to off mode whenever I access Roon

Roon Core Machine

Hello,
Whenever I use my iPhone to access Roon, the master volume goes to the zero level(No Volume). I can reset the master volume on my phone, but as soon as go back into Roon I lose the volume.

I was just curious if anyone has had this issue also, or what might be causing this. It just started a few weeks ago. Not sure if a recent Roon update might have changed a setting to cause this issue.

Thanks ,
