to fully understand what how your products perform you need to know how many returns you have within a year. Further you also need to run analysis which products are returned most or what the most reason was for returning an item.
Showing only the last 30 does not make sense since this picture strongly changes month by month, so you need to get an overview by quarter and year.
Thanks for adding this feature, which should not take too much time since the data is there and the dashboard as well. You only need to add a customer data range.
Many thanks guys!!
