Ted here from Shopify, thanks for reaching out to us!
I'm just after taking a look at the account and it seems that your store is under review. This is a standard review for all new stores just so we can verify that the account complies with our Terms of Service. Our reviews can take a few business days to complete and we are sorry for the frustration caused.
Our general support can not see the review in more detail, however, your request has been raised to the correct department and as soon as there's an update our Shopify Payments team will contact you back via email, ticket #20648828.
