Jessa and Joy hang out with family all the time. Heck, even Jill and Jessa took the kids and had a recent outing. You never see Anna one on one with any of the older girls. She's always part of a larger group.
Anna could have Jessa or Joy over for lunch or something, but we never see that. When the girls visit the Big House, they're not going to visit Anna.
I think they're civil, nothing more.
