Hello everyone,
My organization uses ArcGIS Enterprise 10.8, which can be accessed through internet with web adaptor in dmz. We have lots of public surveys, most of which has attachment questions. In order to keep those layers secure, we made some settings but we realized a problem that if featue layer behind the survey does not have update capability, then attachment are not written to feature layer. As a security settings, we created a fieldworker layer and opened only editing capability, then changed submission url from Survey123 connect. Whenever update capability is not turned on, the problem occurs. We also have ArcGIS Online account, I tried the same process there, and It seems to work okay.
What might cause the problem?
Thank you so much.
