No new published content The RSS Feed service distinguishes between new content and updated content. Applets are triggered by newly published content, while items that have only been updated may be ignored. Below is an example entry from an RSS feed. It was published on 2021-11-09 and updated a couple of weeks later on 2021-11-23. The originator of the feed content may list entries based on when they were updated, but a new connection created with IFTTT after the 9th wouldn't trigger in this case.
