The procedure to Send to bank account has changed. Now you are required to add the bank account details beforehand, which are saved for future use.
In the Add New Bank Account form, the Bank SWIFT Code field requires 8 to 11 characters.
If your US bank does not have a SWIFT code enter 8 zeros e.g. 00000000 to fill the mandatory field requirements.
Make sure you supply the correct routing number and bank account.
