I am attempting to experiment with the new Parcel Fabric in ArcGIS Pro and running into some issues with the feature service. It seems to work the first time I publish the service and added the Fabric to a new project. Editing seems to work as expected but typically, when I attempt to re-open the project the fabric will appear with red exclamation marks next to all of the layers. If I try to add it back to a fresh map I get a 'Failed to add data: 0' error.
I can republish the service and the fabric in the original ArcGIS Pro project will load again fine.
FYI - running ArcGIS Server 10.7.1 on one machine federated with Portal on another machine. The fabric is stored in PostGreSQL 11 running on my local machine (for testing purposes mainly).
