Hi,
So I'm trying to populate a field using an expression. Just to fill it in with the logged in username, so a fairly basic one line expression, which compiles and works fine in the Arcade Editor on the AGOL Field Maps Early Access designer.
GetUser($layer).username;
For some reason when running the app (using iOS), I get the "Failed to Calculate" error on that expression and it won't let me save the record.
Any ideas??
