I have a point layer I want to be the basis of my Inbox for my inspectors. I used this layer, published as a feature service, to create a new Survey123 form. I added a lot of customization, including repeats to allow additional geotrace and geoshape questions that will be related to the original point layer. I could not publish the updated form from Survey123 Connect using the submission_url and form_id, because Survey123 cannot find the related layers that store the repeats. I removed the submission_url and published a new empty set of feature classes for the form instead. I then brought the newly published feature service into ArcGIS Pro and attempted to use Append to add the existing points/attribute to the form's main feature class. But I get warning "000594: Input Feature #: Function not implemented" on every point when running the Append tool. I have verified that the Output XY Domain is "Union of Inputs" and that both feature classes are in WGS1984.
Am I going about this correctly? Please show me how to get my existing points into the Survey123 form feature class so I can use them in the Inbox.
