shopify embedded storefront frame gets "page not found"

Question

I have a Facebook App that displays our storefront in the page. Up until 2 days ago the application was working fine. AFAIK nothing changed either on the FB page or the storefront. Now my FB app shows a "Page not found" error message. The application is a storefront built with Shopify and the URL to the store is https://skydivesnohomish.myshopify.com/ which also works fine. The Facebook application URL is https://www.facebook.com/pages/Skydive-Snohomish/452038620093?id=452038620093&sk=app_285458268248710

Please let me know if this is a known issue or how to debug it further.

Also found that Facebook appears to be issuing a POST to the page for some unknown reason.

Thanks, Tony

See final comment above - I ended up just using a 3rd party app to house the Shopify page.
