Hi!
I've set up a QC template with connected layers. When I'm trying to create a new project from this template i only get "Can't save project due to an unknown error Please try again. If the error persists, please contact Esri Support."
Exact same problem as in: Solved: QuickCapture Project Save As Error - Esri Community
This is the console dialog:
Please email quickcapture.esri.com to arrange a call to troubleshoot this.
