So before the 25.2 releases, everything was working fine.
Currently using Enterprise 11.1, with Enterprise Services (not Hosted).
I have a service that has a Point, Line and a Polygon feature classes in the service. Thats all that is in the Web Map, and the basemap is an ESRI Basemap.
If I manually create an offline area, everything is fine. If I create a Pre-cached work area through the Web Map Settings in the browser, everything is fine.
However, if I create an offline area via python (using ArcGIS Pro 3.3.2 and the mobile_webmap.offline_areas.create command in a Jupyter notebook) when I create lines or polygons in the offline area, Field Maps crashes when you try to add vertex. Creating Points works fine.
Depending on iOS or Android, there are different errors in the logs:
Android:
[DEBUG] Uncaught exception!
Invalid argument. Builder Spatial Reference and Input Spatial Reference: The horizontal coordinate systems of the spatial references are not equivalent. The spatial references must be equivalent or an input null is permitted and assumed to match the owner spatial reference.
java.lang.IllegalArgumentException: Invalid argument. Builder Spatial Reference and Input Spatial Reference: The horizontal coordinate systems of the spatial references are not equivalent.
iOS:

Has anyone seen something similar?
