Almost exactly one year later, I'm experiancing the same problem. I have a map application with a host feature service that is editable for my AGOL group.
I was able to view and edit it with the Collector App, but when by mistake I removed the editing capabilities and later readded them to the hosted feature layer, the map disapeared permenantly from the app. Any ideas for solutions?
EDIT: It seems there ws n issue with concerning the rights on the hosted feature layers. Some layers were open to everybody, others were only for a certain group. I've recreted the app and now it works!
I was experiencing the same problem.
I think If you add a Hosted Feature Layer (with no editing capabilities) to a WebMap and then make it editable it will never be available from Collector (no matter whether it is editable or not). First you have to make the layer editable, and then add it to the WebMap, from that moment it will be available in Collector. At least it worked for me.
If you add a Hosted Feature Layer (with no editing capabilities) to a WebMap and then make it editable, you need to re-save the webmap again to recognize the change of Hosted feature layer.
Thanks! This solved an issue here!
the people who wrote this software should be ashamed! I'm glad their victims gather here for some comfort. (I may sound a bit grumpy but this has costed me a week worth of expensive engineer.)
Unfortunately it is still a thing.. I actually am dealing with this now. How did you get yours fixed? I’m not seeing the maps at all or the layer wasn’t found in arc collector. You could however view it in a web map. Strange... it was supposed to be a quick creation of a field collection map but ended up taking most of my time. Any suggestions are helpful!
In the case I encountered here, I added a hosted feature layer (initially not set to be editable) to a web map. Then, I changed the hosted feature layer settings to be editable. After doing that, the web map still did not show up in Collector. I found this thread, so then I went back into the web map and simply did a Save. Then, the web map showed up in Collector.
Another (slightly unrelated) thing you might have to do is share the web map with an AGOL group that includes the Collector user in the group. Having a web map that is stored in AGOL but not shared with a group will result in it not showing in Collector.
I only had to change the users to publishers and create a group with the map and the users in the group and it finally worked. New install of Portal. thanks very much for the info.
I have a feature layer that is is hosted through AGOL and set to editable. The feature layer was created as results from Survey123. I tried adding the feature layer to a brand new AGOL map and saving the map, but the map does not show up in Collector. I tried saving a copy of the map with the layer and it still does not show up in Collector. I tried deleting the Collector app and re-downloading. The map still does not display in Collector. I am trying to integrate Survey123, Workforce, and Collector. It appears there is a disconnect with the web map created from Workforce to Collector, even though I have them linked through the settings in Workforce. All layers and maps are shared with a group, that I (the collector) am part of. Does anyone have any other suggestions on how to get the AGOL map to display in Collector?
