I am working on building a geodatabase in ArcGIS Pro that will be used as a hosted feature layer by our team on AGOL and Field Maps. Most of the fields are set to "Allow Null" in ArcPro, with a few exceptions. When I upload the web layer and access it in Map Viewer, if I click Create without filling out the few required fields, every single field shows the red alert as though it is a required field. This includes both fields with domains and text box fields (see photos).
If I go to the Map Viewer Classic, all fields display correctly.
