Hi, I am having some issues requesting ImpressionReach for my campaigns.
I understand that this metric does not appear on reports for requests that have a time range greater than 92 days.
The proposed solution I've seen for this is to request impressionReach for smaller time ranges.
If I was to use a time range of say, one month - if a campaign was already live before a month ago, and is still running, wouldn't the impressionReach returned not be for the campaigns lifetime?
If we have a campaign that runs for more than 92 days, how am I supposed to fetch lifetime reach for it?
