Per the latest March ArcGIS Online update, we are now able to build calculated expressions, using Arcade, that automatically populate fields in Map Viewer.
I noticed that this new feature is available in the Field Maps web application as well. Though, after I add an expression to a layer's form and go over to the mobile application, the layer becomes un-collectable and states that "the form contains unsupported data."
Are there plans to support calculated expressions in Field Maps moving forward?
Thanks
