Modern K9 review for GA: Product Addons+Gift Wrap

This is one of the worst apps we have ever used, and we use a LOT of apps. Everything has a glitch. Asked for help and the customer service was helpful at fist then ghosted us. We launched a huge event only to have dozens of calls, emails and complaints. Even lost money in unnessary returns to customers who couldnt shop like they wanted to becuase the app wouldn't work and add product to the cart properly.
