Scandea O2O review for Halloween Day Celebration

Once you install the app, there will be problems when customers are shopping on the site. They cannot click the "Add to cart button", ect. Even if the support team responds fast, they cannot totally fix the problem. I like the style of the design but it is not performing well at all. And i am wondering why they develop this not performing well app and give you the so-called efficient and considerate support instead of developing a well performed app in the first place.
