Does Collector support statistic operator from related tables?

Question

I have set up web map in AGOL with a feature service along with its related table and configured the popup so that i can show sum of values from an attribute of the related table. It works fine on ArcGIS online but when i open the web map in Collector of ArcGIS that attribute is empty.

I could not find any documentation whether this is supported or not in the current Collector app.

Best Regards

I don't think the statistic operator is the reason that the related record is not showing up (not sure if you were convinced of that anyways). In my experience, Collector will not show related data unless the data comes from a FeatureServer type service (from ArcGIS Server). This brings another issue - FeatureServer layers do not support labels. I did not find any documentation about this either. They were hoping you wouldn't notice.

Working with ArcGIS Server 10.2.2 and Collector 10.4.0.
