Hello,
I'm trying to append data to a Feature Layer that I own. When I click the "Update Data" button, it gives me the options "Add Features", "Update Features", "Add and Update", or "Overwrite an Entire Feature". It sounds like "Update Features" is the option I want, but all the options except for "Add" are grayed out, and the message "This feature service only supports adding new features" is at the top of the screen.
Why am I not able to update features? Is this a problem with organizational permissions?
