I have a collector app that is using related data from our enterprise geodatabase (registered) published on our ArcGIS Server. I have added the feature services and their related table onto AGOL (saved and shared). I have manged to access the app using collector, make changes which were reflected on my enterprise geodatabse live. However, when I downloaded the app to work offline, it finished downloading but when I tried to open it, I am getting the following error message "Unfortunately, Collector has stopped" and Collector crashes.
I have tried uninstalling Collector and installing it again but still keep crashing. Can anyone help please?
