I published a hosted feature layer to AGOL that allows users to create, update, and delete point features. Initially, we were able to add a point to the map and complete the fields in the attribute table. However, what is happening now is the data I enter disappears as soon as I click on the next field in the table. Also, the date field auto populates to 12/29/1899 and reverts to this date when I try to change it. Oddly, this isn't an issue when we add a point using Collector - we can fill in the fields, but the date still defaults to 12/29/1899.
I didn't make any changes to the layer's definition after publishing, so I don't understand what is happening. I appreciate any insight on this.
