I've used the Collector-to-Survey123 workflow successfully and created joins in a map on AGOL Online. I'm now trying to replicate the exact same project workflow on Portal. Everything seems to be working on the Collector and Survey123 side, but when I go to join the matching fields in a map, its coming up empty. It seems that AGOL and Portal are treating GUID differently. There are brackets appearing on Portal around the GUIDs and for some reason, these are causing my joins not to work. Again, this works perfectly in AGOL Online so I'm really confused. How can I get these joins to work with or without the brackets? What changes do I need to make for Portal to join these two feature layers?
ArcGIS Portal (Polygon GlobalID has brackets, so does matching GUID field in survey data - yet they won't join)
ArcGIS Online (GlobalID and GUID have no brackets, and joins work correctly)
