It's really bad I have to leave this app negative feedback, the app does not work as described or as expect. It will not update the products feed very well, it does add feed, though. When I contact online customer service, or send email to support, they just provide an expert phone number, and ask to contact expert, but no reply your question directly, or solve your problem in email or live chat.
Your questions were slightly advanced and our customer support executives did not know the answer right away. Sorry about that. We ask you to get on a call so that our experts can answer your queries.
