Hi! Thank you for trying out AmChat. Our team looked into what could have caused this issue, but we couldn't find anything that could be it. It looks like you downloaded AmChat only a week ago, not 6 weeks ago, and AmChat has no permissions to update/delete the products, so there shouldn't be a web sync with your store either. If at all we find the root cause (even if it not due to AmChat), we'll be sure to let you know at the earliest. We will be more than happy to serve you in future. Thank you for writing to us.
