Munk Pack review for Discount Ninja Promo Engine

I would love to be able to use this app seeing as Shopify somehow still doesn't allow stacked discounts, but in the few days I was running it on my site, there were multiple issues and no response from Support. Products that weren't included in my offers were getting discounted and customers were able to use discounts more than once, even though this is not what the settings on my offer specified. I've been waiting over a week for any update from their support team and am just being told "they're dealing with an unusual amount of requests." I've followed up every single day and have been getting the same general response. Out of the 10 days of the free trial, I was able to run the app for 3 days and then had to pause all of our offers due to these issues not being resolved.
