One of the most annoying things that Facebook/Meta has done to advertisers during the past year is remove the "Compare Windows" feature, which allowed you to compare the number of conversions that came in by attribution window.
Previously, you could see how many conversions came in as a result of 7-day click, 1-day click, and 1-day view attribution. If your numbers seemed inflated, you could check to see if it was due to view-through.
Now that tool -- and that context -- is gone. We're left guessing.
