Same issue here, the [done/save] function doesn't work, clearly a major bug. I did a lot of edits last week and everything was dismissed. Tried again today, still the same issue, clear that they shipped the solution before thinking and testing it enough, so full of bugs.
The cost of beta-releases like this will not only be big for us as users, but for brand reputation, more and more issues like this make me think twice about promoting the service for clients...
Hope this will be sorted as soon as possible.
I was hoping to find a [save] shortcut since the button is broken.
