Mine are not back. Well, my wife's and one of my daughter's FPs are not. It shows mine and my two other daughters. They are still in my friends and family list and still shows I manage their plans, but I cannot select (or even see) them when trying to make FP selections and their plans do not show in my FP plans (but do show in my itinerary).
Everything just seems borked. I'm on hold with support going on 20 minutes, but I always fear they'll make things worse when tinkering in my account.
EDIT: now 45 minutes on hold. If they tell me it's widespread and just to wait it out, I'd be fine with that, don't want anything messed up with everything I already have planned.
