But As I said: Even if I change that, there still is default-size when I start working on a page. And the page ́s setting isn't changeble.

Hi. When I create a new build. I choose "Tablet". I look at app properties and resolution says 1024 x 768.

But when I start building on a page I get portrait-mode and can't seem to switch.
What am I missing here? =)
