I think it would be beneficial to align the Weekly reporting filters throughout various parts of HubSpot. If you choose Weekly for a filter metric in something along the lines of Marketing Ads, it’ll show Sunday through Saturday.
However, if you were to choose the Weekly filter within your Dashboard or other places of HubSpot, it shows the traditional work week, which is Monday through Friday.
Although you can choose custom date ranges which will account for this, I am sure there are others who were confused why the numbers didn’t match up from two points in HubSpot.
