19% German VAT charged despite valid EU VAT ID, self-service reissue does not fix it

We are a German GmbH on Pro. Since VAT collection started (April 2026), every invoice, including all AI Gateway credit top-ups, carries "Standard - GERMANY 19%".

Our settings match the Taxes docs exactly: tax ID type "EU VAT number", VAT ID with DE prefix, German billing address. The VAT ID is printed on the invoices. VIES confirms it valid (qualified check, 2026-09-25).

The invoice modification flow reissued our latest invoice with the VAT ID, and the new invoice still charges 19%. Support pointed us back to the settings, which are already correct. We have also emailed tax@ and billing@.

For B2B purchases from Vercel Inc. (US), reverse charge applies. Is anyone else in the EU seeing this since April? And can someone from Vercel escalate it to the tax team?
