@Stephie In your recent comment you messaged me about old post with notice banner, and you told me that you do not know of any mechanism to quickly filter for these for a re-check; I found out in Q&A linked by Nai45 that there is unlisted link to the list of all annotated posts, whether locked or noticed; it is accessible for public and I can see
cooking.stackexchange.com/annotated-posts?tab=noticed even from incognito browser; hope this helps.
