We used this app across multiple Shopify stores and it caused serious operational damage. Shipping rates and thresholds malfunctioned randomly, resulting in significant revenue loss. After reporting the issue, the developer abruptly terminated our access and removed key configuration options from the app, which caused checkout failures for many hours and major additional losses. We’ve opened a formal case with Shopify Plus Partner Compliance regarding this incident. Based on our experience, we strongly recommend avoiding this app until Shopify completes its investigation.

App errors caused serious financial harm to our business. After we contacted support, the developer disabled key features without notice, making checkout impossible. Currently under Shopify Plus review. Would not trust this app for live operations.

Because of the app, all customers were not able to check out—randomly on a day—for a full day straight. While trying to find the issue, I discovered that this app was causing the problem. It clashed with Shopify. Shopify thought no shipping rates were added, while the app was actually controlling the shipping rates. I reported this to Shopify. This is the second complaint I’ve had about the app. I like the app and want to use it, but I’ve already lost over $1K in ad spend (LOST) because of the app. And I have no trust that this can’t happen randomly again.
