As noted in a common above it's a pain in the ass to work with. That's the biggest marketing problem. It's a confusing product that's glitchy.
A user above said it took him an hour to set up, and once it’s set up you’re done so not sure what you’re on about here.

Given the benefit on offer here I think you’re greatly overemphasizing the interface issue, but u do u.
