There are 2 reasons you may not see the buy button on the single product page.
1. If the issue is a digital product, the button may not be appearing because you did not enter the Easy Digital Downloads product short code number. Please go through the steps of how to add a digital product and add the short code number.
2. If the issue is with a physical product, you may have entered an incorrect value in the shipping input when creating a product. If there is no shipping amount, leave the input empty. Do not enter any words, the input is for numbers only. But once again, leave the input empty if there is no shipping cost.
Also, make sure you have added your PayPal information in the WordPress Customizer at Customize > Product Store.
