Report Pundit: Custom Reports

I reached out to the support chat before installing. They said I could easily do the reports I needed so I installed and asked them how todo it. They just kept guiding me to a generic custom report help article without any actual help on it. I tried but it was basically just an overally complicated spreadsheet that couldn't even filter by a product name I had to manually type it in. Was easier to download 18000 orders and manually do it on numbers.
