This is the rejection, word for word: „[UBL-CR-431] Your invoice contains a FinancialInstitution Address element which is not allowed in EN16931 invoices. This element must be removed.

What to have readyNothing. The file has to be re-exported from your invoicing software; we check it again afterwards.
What we doInvoice Navigator automatically removes the disallowed `cac:Address` element from your Invoice.
If you enter it yourself in your invoicing software
Before
<cac:FinancialInstitution>
  <cac:Address>value</cac:Address>
</cac:FinancialInstitution>
After
<cac:FinancialInstitution>
  <!-- cac:Address removed for EN 16931 compliance -->
</cac:FinancialInstitution>

Element order is part of the rule: if the element sits in the wrong place, the validator rejects with UBL-CR-431.
