For a current project it seems that in order to edit the feature service with a lines layer we may need a proxy page. The service is on our local server using an SDE dataset. We are still trying to get the proxy page working properly to test.
But the only place to set up this proxy page information is in the web app template. And collector uses only web maps, right? So is there another way to still be able to edit feature services that require a proxy page for editing? The technicians only have a phone so the requirement is for them to be able to edit attributes either in Collector or ArcGIS app.
