Amai Upsell+ Volume Discounts

The App works well when it works but the functionality breaks every two months and I need to contact them to fix. I will give them one more chance to address and if it breaks again be moving on.

It seems that the discount code box at checkout is disabled (not appearing) when the shopping cart contains products of which quantity discount is applied. I contacted the support team but still waiting for their reply. If anyone knows of a solution please could you share with me?

I loved everything about the customer service and nearly everything about the app.... (easy interface, clear design, elegant, easy to use and navigate) BUT at checkout our customers couldn't use discount codes, and this lead to a lot of abandonment when we were testing the app.and a lot - a LOT - of manual fixing of orders and helping resolve unhappiness. So unfortunately we couldn't use the app :( Would totally re-up if this were resolved and fixed
