Savvy Stylish review for Sticky Cart: Slide Cart Drawer

I wish I can give a -ve star rating for this app. It worked really well for a few months, and then things broke, I mean came to a grinding halt. I am unable to login to their app and make any changes. Customer service exists but barely, and their ETA for fixing a production issue is 72 hours. I don't know how anyone can run an ecommerce store with this type of app and support when you are simply unable to make dynamic changes and see it take effect.
