Dentiphoto review for GemPages Landing Page Builder

Big problem. I have created a landing page, but the shopping cart creates an incorrect design (different from the original store). GemPages shopping cart design is terrible. Emerald in support did not help me and told me to solve the problem myself. Support claims that the cart is managed in the main Shopify theme, but I don't have that. There is an error on the app side and they are not solving it. I paid 59 dollars, spent a whole day doing the landings and now I'm going to lose time and money.
