i'm using Magento 2.2.2 and when i add a product to cart, i can't found a Paypal option between payment methods. I enabled Paypal express checkout in mini cart or in product page and i can go to paypal site and pay. What can be the problem?
So does the paypal button shown on the product page and in the cart, but not in the actual checkout? Is that the problem?
PayPal express can only be shown on these areas, it cannot be shown in the checkout. If you wish PayPal to be shown during the regular checkout process you will need to enable another PayPal payment method like PayPal Payments Standard.
