I have installed the previous Version 2.1.0 that is working normal. That means the issue was definitely occurring because of plugin’s latest version. Please fix it. When the woocommerce custom order is added, it does not show paypal payment method, it shows an error that payment method is not available at your location. However, it works when we go to website and add the product to cart and checkout it. But custom order is very important for every business, payment method option should be fixed for it.
