Hello @AprilChipman
I haven't been able to make it work for my data. I think it could possibly work for grids or if each polygon in the feature class/service has the same amount of vertices. At least that is what I gather by reading the documentation. I have restructured the workflow of a few of my surveys to have the survey write to a related table of the feature class/service, but then you have to get into writing a view if the data are not hosted in AGOL. Another Survey I have set up to be opened in the S123 App Survey Inbox - so they would select the polygon in the map or list after refreshing the inbox.... So I have found other ways, but they are not as seamless as the way I have surveys that pull in the geopoints with Custom URLs.
If anyone else has solved this, or finds a new post about alternatives I would love to know.
Thanks
