OC Quantity Breaks Order Limit

I need to offer volume based pricing at a variant level. This app solved this, however it is a pain working with it. It takes forever to do the slightest change and its messing up my UX having it take forever to load and apply the pricing rules. It was way better when I started using it. I dont know what changed they did, but it definitely didnt improve. I hope they do something about it.

Installed the app and had problems with cart; any time a customer tried to change an amount, it automatically would go to checkout; also, a customer could not delete any product from cart.
Reached out to support and waited 24 hours. No response, even though it shows they had been online an hour earlier.
I uninstalled the app and went to a competitor which is working fine and does exactly what I need it to do.

We set minimum order quantities for certain products. Several times customers have been able to cash out when not meeting the minimum requirement. We then have to go and explain to the customer and cancel their order. It's super frustrating and when I reach out to the app for assistance, I have never gotten any help to fix the problem. Their response time is so slow. Unfortunately we will be finding another app that can do this.

Didn't work for us. be weary if you have the 'Warehouse' theme. They did try to fix it and said they'll get back to us by end of day Monday... end of day came and we didn't hear anything, we messaged them and still no reply about the progress. We had already waited a few days for them to fix the issue and couldn't wait any longer as we need an app that works.

Warning! This app bugged my Debut Theme. My customers were having trouble with adding items to their cart and removing items. I had to contact customer service and they fixed the problem
