My developer account cannot register any App ID at all. Every attempt in Certificates, Identifiers & Profiles fails with:
"An App ID with Identifier 'X' is not available. Please enter a different string."
Facts:
- This happens for EVERY identifier I try, including deliberately random test strings such as "music.sonicoracle.zzztest" that cannot plausibly be registered to another team. So the identifiers are not actually taken.
- My Identifiers list is empty — nothing has ever been registered on this account.
- Certificate creation works normally (Apple Distribution cert issued without issue), so the account is otherwise functional.
- The failure has persisted since my membership activated on July 27 (Individual enrollment, paid, active), and continued unchanged after my account completed a full re-verification (legal address change, identity re-confirmed) on August 10.
- Free Apps Agreement active; Paid Apps Agreement signed and processing; all tax forms active.
The identifier I actually need is "music.sonicoracle.app" for my own domain (sonicoracle.music), but the issue is account-wide, not string-specific.
Developer Support case: 20000121583142 — so far I've only been pointed to documentation, which doesn't apply; the registration flow is being followed correctly.

Has anyone seen an account-level App ID registration failure like this, and is there a way to get it in front of the team that can inspect the backend state of the account?
