App just crashed, had to disable this and resort back to Shopify delivery. I would guess we lost hundreds worth of sales. What was the absolute killer, there is no immediate support for this app. We had to write in, create a ticket and wait without any immediate support. Not too great.. good while it lasted.

This app is great. Exactly what I want to calculate the shipping fee by distance. But recently, it has crashed twice already. It is very frustrating for our business to see customer walks away just because they cannot pay the shipping fee.
