Thanks.
A). iOS 10.3.2. iPhone 7 model MN9T2LL/A
B). I understand normal do not disturb functionality and do use scheduled do not disturb periods at night. I have tried disabling favorites and not allowing repeated calls and so forth but it's not just from favorites so disabling favorites has no effect and it's not second calls so that isn't it either.
C) I believe this is a bug not a user error, though I may be wrong, for the following reason:
D) This is repeatable. ANY face time, whether from a favorite or not, does not respect do not disturb. On the first attempt at face timing, not the second. My sons have the same problem.
Thanks!
