Advance Order Quantity Limits , 18 reviews

Great app concept but causes huge performance loss over all pages in regard to page load times, including pages that have no products or product links on them. Page loads crept up to 5 seconds! Once the app was disabled, pages loads returned to under 1 second. We spent weeks trying to optimize our store, tried multiple themes, optimizations, and "expert" evaluations, and finally realized the problem. The app has to be disabled from the customization view, not just in the app settings. To be fair, we did not reach out to the developer once we finally found the problem, since we can live without the app and it was so detrimental to our business. Just leaving the review in the hopes that others don't go through the type of problems and unnecessary expenses and revenue loss that we went through, and that the developer is able to fix the problem.

So another review was "spot on!" Great app concept but causes huge performance loss over ALL pages in regard to page load times, including pages that have no products or product links on them. Page loads crept up to 5 seconds! Once the app was disabled, pages loads returned to under 1 second.
The app has to be disabled from the customization view of your "online store" THEME under "app embeds", not just in the app settings. To be fair, I reached out to the development team to ask if the app was the problem/if it could be fixed, but the 20+ hour time difference/delay was just too much. I'm impatient. I disabled the app embed, and my product pages loaded within a second afterwards. So I'm leaving a similar review in the hopes that others don't go through the same problem. The other review was left in November so it doesn't look like the developers have been able to fix this problem sadly.

Works initially, then when you reach the checkout page, customers can then adjust the quantity outside of the parameters you set. Asked for customer support, there response was "uninstall the app". Not ideal.
