Hi @Dirk-Pitt ---- Thank you for the report and my sincerest apologies for the slow response here. The feedback is appreciated and again, my apologies for the tardiness.
Moving forward, may I very kindly ask you to please provide me with a brief but accurate description of your current setup using this link as a guide.
Additionally, based on your report it sounds like this behavior is being observed on your Roon remotes. During your troubleshooting of this issue have you tried reinstalling the application on the Windows and iPad pro remotes?
