"Your ad was shown to 2 people" but it was 1 person. Multiple that by however many haven't linked their accounts, and FB is charging you^W advertisers twice to show the ad to the same person.

TFA: >If only a small percentage of your target audience has linked their accounts, when you run Facebook and Instagram ad campaigns, you'll (falsely) see that you're reaching double the number of "people" (i.e. accounts). After all, Facebook will count that one person as two, if your ad shows both on Facebook and Instagram.
