I created a shapefile called random points in ArcMap. I assigned it a coordinate system, and I then shared as a hosted map service. Under Feature Access I checked Create, Delete, Query, Sync, and Update. Under the Sharing tab I checked the appropriate group.
When I accessed the Collector App, I was able to see the points I added as well as see its proper spatial location.
Though I was able to delete or edit a point, I was not able to see the add point feature. Under settings I also checked Add, Update, and delete features.
When I add another feature class I see the Add point feature in the collector app, but for some reason my recent created layers don't have the tab shown up.
I wonder if it's something I did not check off or took into consideration when creating my layer.
