Hi there, I purchased this, it seems promising, but buggy.

First question - is the website builder only for single pages? Or how to switch pages? It seems really designed for single page websites, I can't move to any other page or find any other pages or maybe I'm missing this.

How do I contact support?

Could you also shed any light on the following issues and if they can / will be getting investigated / fixed?
-Sections getting frozen somehow after changing a size (AI can't change it, Undo does nothing and Discard all changes not working)
-Navigation not previewing on the preview link (just saying the system message that navigation will go there)
