Apple ID 2FA on Chinese Windows — code screen, but no code
On 1.1.3, sign-in reached the verification screen but Apple never sent a code (#5). 1.1.3 had fixed the latin-1 crash, but left Windows locale display names like Chinese (Simplified)_China in place because they are ASCII. Apple's trusted-device endpoint returns HTTP 500 for that value (proven live); the same request with zh_CN returns 200. Locales are now mapped to Apple-style tags, and a failed 2FA trigger is reported instead of claiming a code was sent.
Update to 1.1.4 and sign in again.
