Hello
I have a question, Does Field maps support the Utility Network?
According to this article What’s new in ArcGIS Field Maps (June 2022) (esri.com) the UN is supported since ArcGIS Enterprise 10.9.1+. I'm using the ArcGIS Enterprise 11 but when I opened the web map (that contains the utility and subtype group layers) it does not work and seems that it does not support the subtype group layer.

Any advice?
