Hi Elliot!
Yes, I am referring to field group sort order.
I don’t recall using the drag/drop, especially since this field was appearing at the top (I never would have dragged it there), but a couple question about that:
1) Is the drag/drop sort order stored in the user or a cookie? I had a client log in using the same username on a different PC and she was seeing the same thing.
2) If the drag/drop was used, is there a way to restore control to the sort order of ACF?
