Does family sharing spending consider activity?
As according to terms, "You have 18 months before your Aeroplan points expire if there has been no activity in your account - meaning you haven’t earned, redeemed, donated, transferred or converted any points. But so long as you stay active, your points won’t expire at all."

In a family sharing account setup with Users A and B, if user A and B both have some amount of points in balance. User B redeeming via Aeroplan, which deducts points off both user A and B, does this reset the 18 month activity count for both user A and B?
