If you submitted an observation only to realize that you had accidentally chosen the wrong value you can now correct the issue yourself! For data older than 24 hours you will need to enlist the help of an Administrator at your site to modify or remove data.
At the top of the Audit page there is a link to view "My recent submissions" and a counter indicating how many submissions you've made during this session.
Clicking on "My recent submissions" takes you to a page that shows submissions made on your specific device, submissions made by your user account in the past 4 hours, and submissions made by your user account in the past 24 hours.
Clicking on any of the listed submissions opens that submission in an editor that allows editing or deletion.
Note: The past 4 hours and past 24 hours options will show any submission for your user account. If you use a shared account this will show submissions from other people sharing the account.
