Age Verification Expired ID Problem

I can’t find anything specific on expired IDs my guess the answer will be you likely need to get a new ID. Given the Age Verification FAQ is now very much closed I don’t think you’ll be getting an answer until the program is expanded: Developer Update - 16 January 2025

As for Alt accounts that was answered back in this video here:

In other words Alt accounts should be allowed as verification is fully rolled out.
