Thanks! I found it, and it definitely changed the sorting but to what I can’t tell… Items def aren’t in descending order by publish date because some from 4/17 are at the top of the first page and 4/18 is after…there are also strange empty spaces in the grid now.
Are date and time both taken into consideration too in the ‘publish_at’ command? Also, some of these Items were set on the 16th to publish on the 17th so I wonder if using the tool to publish in advance messes anything up?
