Upgrade from Draft to Published in 3.x

I wrote a post in the new iOS app and saved it as a draft. I then only got the option to edit and save, not publish.

Am I missing something or is this a gap?

Or could it be something not showing in the UI for me (like the magic space in the upper left that is blank but brings up a menu when you click…I assume this is not invisible for others like it is for me?)

To publish a draft in 3.0, go to the Posts screen and swipe left on the post. That will reveal a Publish button.
