I can't find anywhere how to allow users to edit or delete their submissions.
How come this is under Tips & Updates?
You can do this in the dataset permissions. If you allow edit and or read, you will be able to edit the info. Then all you have to do is program a button to the dataset to allow for either a save or delete action.
I realize that. I was just trying to figure out how to show the edit or delete button in a repeater only for author
