I am having difficulty exposing my hosted feature layer's related table for editing. I have tried republishing several times with different permissions and everytime the edit check boxes are unavailable in the ArcGIS Online Pop-Up (configure attributes). I want my features to remain unchanged and would like my inspectors to simply add a related record everytime they inspect the feature. I'm really at a loss as to why I can't enable this. I'm thinking the permissions may need to be added on the SQL Server Manager but I have tried that as well. I'm really just taking a shot on GeoNet because this process should be straightforward and it continues to frustrate me.
Any feedback would be appreciated.
