I am seeing that it still works, but is a little finicky, so if you're experiencing this, I'd say just be very patient and go through all your steps.
Mainly I am finding that it isn't really saving the edits I make so I try and click out of the window, and then click on apply, and then maybe I refresh the screen to make sure that the edit is still there... it's a process. It's been this way ever since they introduced a "done" button in the groupings area a month or two ago, and then removed the button shortly after.
It feels like somehow, something in the system is still expecting you to click "done".
You're certainly welcome to post your code if you feel there might be something wrong with it, as well.
