Field validation issue in “PayPal Checkout” plugin for WooCommerce

When attempting to make a payment and required fields in the billing and shipping information are missing, clicking on the payment buttons simply scrolls me to the address section instead of receiving an error message indicating the missing fields.

I’ve checked the plugin settings and haven’t found an option to enable field validation before proceeding to payment. I’ve also compared this behavior with another PayPal plugin I used before, and that plugin correctly displayed error messages when fields were missing.

To reproduce the issue:

1. Add products to the cart.
2. Proceed to checkout.
3. Leave required fields in billing and shipping information blank.
4. Try to proceed to payment by clicking on any of the PayPal payment buttons.
