I am trying to make a very simple web app, consisting of a single layer (and basemap) where the public can edit attributes to 'claim' a survey zone for themselves. I have enabled public editing on the feature layer, set it to editing attributes only, and set the layer and webmap as shared with the public.
When I create the web app, there doesn't seem to be any option to edit the relevant attributes!? I did this successfully two years ago, and it was easy, a member of the public, upon opening the map, could simply select a survey zone of their choice where a pop-up appeared, showing the attributes, and allowing them to edit the relevant ones to claim it for themselves.
Now, the pop-up appears, but there is no option to edit the attributes. I must have missed something but I can't see what it is. Can somebody point me in the right direction? Thanks
