Collector seems to not work with ArcGIS Server secured feature services for some reason. The webmap opens fine and can edit/add features using collector "classic" without any issues. Popup when opening map in collector says:
"Secured Layers you need to sign in to access some of the layers in this map." Select "view" and it takes you to the layers list with a orange triangle. Touch the triangle and get a login box that does not reference which ArcGIS server is asking for the credentials. Enter my username and password and it seems to make contact with our ArcGIS server because the symbology in the legend looks correct, but none of the features ever load.
Anyone gotten this to work for them?
