I checked this for you and PayPal should be available for you to add it as billing method. Could you please click Add Method button in your Billing Methods Settings and then scroll down to see PayPal option as shown in this screenshot:
Hi, I am having the same problem. I cannot pick PayPal as a billing method because I only have the credit or debit card option. I hope you can help me resolve this problem. Thank you
Could you please confirm if you are trying to add Paypal as a billing method to your client account? If Paypal is not showing as an option, it means that Paypal is not supported as a billing method in your location.
