The calculated and editable expressions configured for the same field do not execute in ArcGIS Online Map Viewer.

Workaround

1. Set the calculated expression to:

return $originalFeature.ID

Now the calculated and editable expressions perform as expected in Map Viewer, perhaps because $originalFeature returns the previous state of the feature being calculated, avoiding the order of execution infinite loop.

2. Reference a different field other than the field being configured in the form, for example:

Reference $originalFeature.test instead of $originalFeature.ID in the calculated and editable expressions.
