I have a feature service hosted on our own server. I'm able to see the service on AGOL and load it as a feature layer in a web map. I'm able to edit the feature layer through the web map interface. Sync capability is enabled. When I log into Collector on my mobile device, I can see the web map I published with my feature service, however, when I open the map, none of the data shows up. The layers are all listed in the layer list, but they're all disabled and I can't turn them on. When I try to download the map locally to the device, it errors out. What is the problem here? Why does everything work fine online but not in Collector? Thanks.
