There seems to be alot of gaps (missing pieces of data) in your feed, that may be preventing many of your listings from being being posted at some syndicates. Contact me and I will run it through our feed validator for you.
I'm sending you a reply through your ticket. Your mhbay.com feed is live, and we are looking into why your listings are not displaying. If you have any questions, please reply to the response you get in your email.
I've forwarded this question to our Customer Service team so they can verify the status of your feed and listings. I expect one of my colleagues to post another reply to this post later today.
Thank you for your patience in the meantime.
