On July 16th, we’re fixing an issue where newly published islands that had been unlisted for 7 days or longer surfaced in the ‘Updated’ row instead of ‘New’ in Discover. Going forward, your islands will appear where they belong based on the precise time of visibility.
In the meantime, when publishing new islands, be sure to set your islands’ visibility to “listed” anytime within the first 7 days in order to be eligible for “new” Discover rows and new content testing
