I have a layer in AGOL. One of the fields is set as non-nullable. In the layer properties in AGOL I can see that the field is non-nullable. However, when I collect a feature in Collector, I still can skip the field without any error message.
Michael, in my understanding this functionality is not available at present but has been raised many times - it is something I am also hoping to see implemented. There are some suggested workarounds..https://community.esri.com/thread/122174
