I'm sorry to hear about your iOS/macOS problems. I'm using an iPad to run Innuos Sense, and I can access my.innuos via a MacBook Air when necessary. However, I use Innuos Sense exclusively to run my music player, and it has been working extremely well. The only time I have had a problem was when I initially tried to use the my.innuos screen on my MacBook as a way to control my music player (since it looks a lot like the Innuos Sense screen on my iPad). As long as I access music files through the iPad only, things have been fine. I have no idea if anything I've mentioned has anything to do with your Innuos issues, but I thought I'd describe my experience in case it is helpful.
The other issue I wondered about is whether you might be having any system network problems, especially with intermittent wi-fi. You've probably already covered the basics in your troubleshooting efforts, though, so my thoughts may not be helpful.
I don't use Roon, but based on the comments of other Innuos/Roon users, the new Innuos software should provide better overall sound quality than Roon does. To get better sound quality than your Zenith is likely to require a greater financial investment.
