We installed the app and were in contact with a member of their team. He noticed that we were using other plug-ins and proceeded with manual customization. Apparently, no testing was conducted after making these changes. As a result, our entire front page became non-functional, and product images failed to load. This issue cost us a full day of revenue. Completely unacceptable.

It's not working even on Shopify Dawn theme... He didn't even tried to make it work. Each consequent "fix" will decrease my store speed to around 50. Even if the app doesn't work, they still charged me. The first answer was a recommendation to just uninstall the app, which say a lot about their ethics.

Hello, We eagerly installed this application with high hopes. We made all the adjustments, but apart from a 1-2 point improvement on our website, there hasn't been much progress. We've been trying to reach the support team for two days now, opening tickets through the support section and sending emails to their addresses, but we haven't received any response or assistance whatsoever. Frankly, when I read the reviews, it doesn't seem like this at all. Either the reviews are fake, or they no longer care about this application. In short, the application is not functioning, and moreover, you can never reach the support section.
