Hi Chris, your post needs to be moved to the Support area and tagging @support will also help highlight it. There are a lot of very helpful people in the forum Chris, hopefully they can sort out your issues quickly.
Could a mod please move this to the support area. @andybob Chris is obviously very frustrated
Have a read of this as support will want to know more about your set up: I'm having a problem with Roon -- where do I report it?
Chris, does your Mac Mini go to sleep? This maybe causing issues?
