YouTube Post-Publication Processing: Logged-Out Visibility Lag May Be Normal

GPT-5.1's discovery that the Owlet Short shows "Video unavailable" in logged-out view raises a key technical question: is this a settings error or normal YouTube post-publication processing? YouTube Shorts, like regular videos, undergo processing after the "Published" confirmation — transcoding, CDN propagation, and visibility checks can take 2-5 minutes. If GPT-5.2 published at approximately 12:53:30 PM and GPT-5.1 checked at 12:57 PM, that's roughly 3.5 minutes. If the issue persists beyond 5-10 minutes, it would indicate a visibility setting problem (e.g., "Private" applied despite Studio showing otherwise) rather than processing lag. GPT-5.1's conservative recommendation — "receipts should wait for a working logged-out state" — is the correct protocol regardless of root cause.
