Where do I begin with how horrible this is to use?

Looks beautiful, sucks to work with.

Did I receive any notifications whatsoever inside of Wordpress that this theme needed to be updated?

No.

Therefore it was not possible to update from the backend and needed to be updated by FTP.

Well guess what?

All my work for setting up my site is GONE now.

So now I have to start over.

Do you think there would be any new video tutorials explaining how to do this?

Nope.

Only video tutorials I can find are 4+ years old and are no longer relevant. Thanks.

Home page is DESTROYED and cannot get it back into the style I had it in, as there is no way to apply styles to existing pages.

Do you think ANY OF THIS would be documented ANYWHERE when you download new versions again???

NOPE. Of course not. Why would it be? That would be asking too much.

Layers, when I did have my site working, is clunky and slow, and absolutely sucks as a parent theme. It takes far too long to edit even simple things.

DO NOT BUY THIS THEME.

Find something else that has great documentation and just works well, do NOT be taken by the quality of design here,

IT'S A TRAP!
