Expédition UPS (Officielle)

I want to use this app, but it ALWAYS incorrectly rates our shipping costs even as we've tried multiple times to synch it to our UPS account. We've become accustomed to this. However, the app often loses synchronization with Shopify and we are unable to fulfill orders received in time for EOD shipping. Kind of sucks when the UPS driver has to come back the next day because the app doesn't work.

The App doesnt work as smooth as it should vs their competition. The main issues Ive seen are reading orders incorrectly from Shopify (especially with orders with several items) and certain orders dont get auto-fulfilled in Shopi when printing labels in the app (and we still dont know whats triggers this problem). Eitherway, this happens in a short amount of orders but I think it should get improvements.

Regarding the CS support, the service has been great and helpful.
