I was wondering if anyone else had been able to join field data using ArcGIS Pro to a hosted feature layer. I am trying to add a field and some data to a table that I shared as a service to AGOL. In ArcGIS Pro, I created a project with the hosted data and then added a table which has the relating field and then the column that I want to add. I know that it should work, because I can add it as a temporary join, but when I try to join the field, I get error 999999, and tells me that I don't have permission to execute the operation. I am the owner of the hosted feature service, so I am not sure what the issue could be. Any thoughts?
