In version 2 of the Survey123 app, there is an option to update surveys after submission however I have been unable to get this to work. The error code is 1009 (as per attached screen grab). I have done some searching but cannot find anything to explain this error. My thoughts are:
(1) perhaps this function is not possible in a public survey. There is no mention of this limitation in the blog announcement.
or (2) I may not have the settings for editing/updating the feature service correct. See attached.
