Why can't I connect my commerce account to Facebook?

[sunoncanvas]

Hello,
I have been facing an issue to connect facebook shop to my shopify account. Basically I am getting an error " Your Facebook Commerce Account wasn’t approved
Facebook has flagged your account because it doesn’t comply with their Commerce Eligibility Requirements. Your shop won’t be visible to customers on Instagram or Facebook until your Commerce Account is approved." 

When I am clicking for the review, a page is opening with a error: " Account reviewed. After a requested review of this commerce account, we confirmed that it doesn't comply with our Commerce eligibility requirements, so your shop isn't visible to potential customers."
AND
"Items not available for review. Your items are not available for review." 
Even I am having Shopify Commerce Account. I have items in catalogue but still this error is occuring. I am not able to publish my shop. Please help me out ASAP.
