Be Createful review for Order Picking App

I'm not one to leave reviews especially negative ones but this app has been extremely frustrating. We've used this app for over a year. It use to work well, but over the last 4-6 months it's become very frustrating, costly and a waste of time. It duplicates some products in orders, so staff will spend time picking 60 pieces only to find out it was 30. It doesn't clear all orders, and several more issues. We've been trying to work with the app developers and get nothing but push back and say it's not their problem. We've gone days and weeks without it working correctly costing our company lost time, productivity and money.
