(On the Insights page on the webapp) 1) Incorrect calculations: when toggling between date ranges ('this month,' 'last month') it will select, for example, Oct 1 - Nov 1, rather than Oct 1-31. The sums will then include not just October's bookings, but ALL of November's, so 2 months' worth. Severe miscalculation, and will make you think you're doing a lot better than you actually are if you're not aware it's in error. Lower priority / less of a problem: 2) You can't really select custom dates, it won't allow you to choose dates in the middle of the month, just the 1st & last of the month. Also, on the 'Period' pull-down menu, there is no option for 'Custom' shown, you just have to take the leap of faith that selecting your custom dates on the calendar on the left will switch it to 'custom' automatically.
