Same here (Czech Republic). My address contains diacritics and after the error message on that input field, removing diacritics > submitting, I see that Apple changes the chars, e.g. from "s" to "sh" where š would normally be. Submitting the corrected by them variant leads to the same error. I wrote to finance with the error flow description and referring to this thread.
[Update] Reply from the Finance came instantly with the following solution that worked:
Hello,
Please attempt to make this update from the Agreements tab, and not the banking tab.
- From the AGREEMENTS tab, click on the paid agreement’s name that requires a banking update. Examples are “Paid Apps”, “Paid Books”, “Music”, “Video”, etc. You have to click the words (agreement name) even though they do not have a blue hyperlink.
You must be on the AGREEMENTS tab, not the Banking Tab
-
Under Bank Accounts on the AGREEMENTS tab, scroll to the right and click Edit
-
From the Edit drop down menu select from:
Edit Current Account
- Update your bank account holder address
If the message asks you to verify your banking, click SAVE again. If the message persists, please click save 3 times. Please be sure to let the page refresh before you click it again. This should resolve the issue.
