Today I try to sell something at auction house with USD and in the option I choose PayPal. After that IE browser pop up, I'm linking payment with PayPal method. After I sign in with my PayPal Account, there is statement/ agreement which showing that my billing address will be provided to Blizzard by PayPal. Then I agreed with the terms & conditions.
Finally, the screen goes back to my Battle.net account page and display error message:
"An Error occurred while linking yout PayPal account.
Your PayPal account could not be linked at this time. This may be due to a system error, or because you've already linked a PayPal account to this Battle.net account."
Please response with solutions ASAP. Thank you.
