Hi,
I have created a survey form in Survey123 Connect that had several "required" fields before it was published. After publishing and collecting data which generated a new feature layer, however, I found that in the field settings in AGOL the settings allow null values. I don't think I would have noticed -- the form works properly and doesn't permit a survey to close without a value in the required fields -- but I also have a Data Interoperability workflow (FME Workbench) in which I have a Writer that uses one of these fields for an upsert feature operation -- but because the field setting is "allow null values" it won't work.
I've tried republishing the survey and nothing changes.

Thanks in advance!
