Why Does WordPress Make it Impossible to Add Posts?

I started to add a post to this blog over 2 hours ago. I was trying to paste an article here that I composed on my iPhone. I used the new interface and the Visual Editor and everything was screwed right from the beginning. Nothing pasted correctly. And it was impossible to add a link to the article. This toolbar vanished from the screen in the new interface, never to be seen again.

Toolbar gone in the new interface

So I guess trying to save time by editing outside of WordPress to save time to a futile effort. Thanks a lot WordPress.com. Up yours too.
