New format doesn't work on iOS devices

The new format looks interesting, but it doesn't work on iOS devices.

The iPad Safari browser doesn't allow editing of posts. Neither does the formatting bar come up when replying to quote previous posts or put text formatting on.

Alternative browsers like iCab or Atomic show the formatting bar, but the keyboard doesn't pop up so it's impossible to make a post or reply.

Same on my iPhone.

I hope this is sorted out very quickly.
