Could you please check your PayPal account and the preferred payment methods you have set in your Wallet. You may also contact PayPal customer support to check if your account is set up correctly.
I checked this for you and PayPal should be available for you to choose it as your billing method. Could you please clear your cache and cookies or log in with another browser to check if you`re still experiencing the same issue? Please use this link to see the options available to you.
Let us know if the issue persists.
Just to clarify, do you need help with connecting your PayPal as a billing method? It is always great if freelancers can check with their banks if their accounts are enabled for international charges.
If any help is needed, let me know. Thank you.
