Paypal chained payments checkout

I am using FlexMarket. I have Paypal Chained Payments enabled and my credentials entered. I just submitted my application for the Application ID.

During the checkout process on my site (vib.in/store/shopping-cart), the Paypal login page doesn't come up for the Billing Page. It only has a form to enter a credit card. Will this change automatically once the Application ID is entered or is there something I'm missing?

The other issue is that I can only add items to the cart and see them through my Super Admin login. How can I have it so that any user or anyone not logged in can add items to the cart and goto the shopping cart to check out? Currently, users and non-users outside of the Super Admin don't see anything in a store's cart when they add the products and subsequently can't check out.

Thanks!

Best,

Ashish
