If I have set Visitor engagement expiration to 1 day will it expire:
a) 24 hrs after last interaction
c) next midnight: day1 enter site, midnight the clock starts counting expiration, when day 3 starts game is over and last engagement is expired
d) something else
1 day = 24 hours.
Marketing Channel: the value will expire in 24 hours after the Visitor's last hit
