Hi Noris,
The issue is I don’t keep the old nuc in my house anymore, so cant move my Roon server back again. I can of course transfer somefiles back to my NAS but understand this is not the issue.
The SB version, I also get the info its the latest version, believe it has something to do with location.
I do hope your QA soon clarify the course to this volume issue. I just start wondering however, if it has something to do with using the Ipad as remote controller, even it has always been the case.
