You are most welcome. This is getting weirder.
This morning, full of holiday food, I changed the filters to show post you authored and still do not see that post. However, learning to use filters is handy in some situations like this, Example:

Then I tried what usually works in spite of any forum search limitations: a site-delimited web search using this string that usually works:
Username +"username”+"2010" site:discussions.apple.com
I changed that template to your username and 2023. It still is not returning a Nov 16 2023 post nor ones with your username other the this one. Weird
Have you asker the Mods to change your username? I'm not surprised that the internal search missed something, but the web search is usually reliable.
If a thread you authored is deleted for cause, you will get an explanatory email to the address you use to sign in here. If that is not your usual email address, check the one that is your Apple ID.
In the past we occasionally saw a moderator error when a single answer in a thread from a responder is reported as inappropriate and a mod accidentally deletes the entire thread. You may not get an email if this happens, but that is a very rare occurrence any more with our current and awesome team of Mods.
