Generally in inaturalist you can order observations by the date the organism was observed or the date when the observation was added to inat. These aren’t the same thing because an observation can be added to inat long after it happened. But for projects in particular, can you order them by date they were added to the project?
I think you should be able to by (on desktop) navigating to the project>observations>list and then toggling the “observed” or “added” columns
“Added” here is organizing them by when they were added to inaturalist, not when they were added the project in particular. I know this because in my arthropod predation on vertebrates project, the observation of a cockroach attacking a gecko is on top. It’s the most recent chronologically but it was one of the earliest ones added to the project
Pretty sure this isn’t possible in the web interface.
