PureFlow review for Aftersell Post Purchase Upsell

Support is great, but the functionality of the app is lacking. I would like to see more flexibility with upsell styling and formatting. I would also like to see a proper mode to A/B test full upsell funnels instead of just upsells within a funnel. I feel like the upsell options are more designed for impulse purchases based on discounts instead of actual thoughtful flows
