Not recommending the app to anyone. Contacted support about 3 weeks ago and the issue inside the app still isn't fixed.
Hannah from Shopify already told us and the user that the issue is not at app's end, its something at Shopify's end.
Shopify's line item system is not showing some orders and they assured you and us in a common email chain that they will fix it asap. They didn't gave a timeline though but they will fix it.
User told us that he will delete this review when Shopify will fix it.
Although its not app's issue but we accept it as we are a part of Shopify and we would love to take equal responsibility.
Sincere apologies for the inconvenience.
The app seemed to be good but once installed doesn’t work for me , any refresh helped, finally desinstalled
