Price for a newly created variant shows after 10-20 seconds on store

Hi,

We have created a public app to help Shopify store owners to allow their customers to buy products and the price is dynamically calculated at the time of the checkout process based on the inputs entered on the page. For this, we use the Shopify public API to create a new variant with the dynamically calculated price. However, we do see that when we create a new variant using API and then to the cart, the price on the cart page shows the price as $0 and no image for up to 10-15 seconds. Then if we refresh that page couple of times, it shows the correct price. It seems like a delay in the system somewhere from the time when the variant is created and when that information is available on the store front end. 

Is there a solution to this or any recommendations?
