The checkout form stopped asking questions that are not yours

The purchase screen showed everyone the same ten fields — contact name, postal code, a separate EU VAT number — and left the buyer to work out which of them applied. The form now knows who it is asking: someone buying for themselves from outside Türkiye fills in three fields, with country and email already filled. Ticking "bill this to a company" opens the tax number, contact and postal code. On a domestic sale the tax number is asked either way — the invoice cannot be issued without it, and hiding it would only make the form impossible to submit.

The tax number is one field now. The same number used to be requested twice — once labelled, once unlabelled below the postcode — and when an EU company did not notice the second box, its invoice was recorded as something other than a reverse charge. The field is still named for your country, so a buyer in Germany reads "VAT ID" and one in the US reads "EIN".

One quiet bug closed with it: on a second purchase the address box was filled with your first invoice's address joined together with its city and country, and that joined line was then appended a second time to the next invoice. The address now comes back only from where we stored it as an address; where we are not sure, we leave the box empty rather than filling it with a guess.
