It messed up my website by constantly refreshing, causing me to lose many customers. I removed the app from my store, and everything returned to normal. When I tried to reinstall it to see if it would work, it asked me to buy another membership. I had a one-year membership, and these guys say if I remove the app, they can't refund or reinstate the membership I fully paid for. Don't trust the high reviews; I believe most of them are fake. I will contact Shopify to get my money back
