I have 3 WKInterfaceController (A,B,C) and hierarchical navigation. So user goes: A->B->C.
Then user can tap the upper-left corner of the screen or performs a left-edge swipe and by default he will go C->B->A.
But I want to skip B and use popToRootController - so I need C -> A.
popToRootController in didDeactivate does not work. Any other ideas?
