I can't add my bank account to the Paid Apps Agreement in App Store Connect (Business > Agreements, Tax, and Banking). Country Turkiye, currency TRY, bank T.C. Ziraat Bankasi A.S. My IBAN passes validation, but saving fails with "Bank key doesn't exist".
The branch doesn't appear in "Search for Your Bank" (searching Ziraat in Istanbul returns the maximum of 50 results and my branch isn't among them). Entering the bank code by hand in the format the search results use (0010 + 5-digit branch code + 034) returns the same error.
I contacted Apple Finance through Contact Us on November 4-5 and again today (November 10) and haven't received a reply yet. Without the bank account the Paid Apps Agreement stays pending, so I can't offer subscriptions.
Another developer reported the same error with Turkish banks here: https://developer.apple.com/forums/thread/850196
Has anyone with a Turkish bank (Ziraat, Garanti or another) solved this? Did Apple Finance add the branch on their side, or is there a bank code format that works?
