Hello ArcGIS Online Team,
We recently stumbled into an issue where 'Calculated Expressions' and 'Editability' cannot exist together. This causes a fairly large issue for those who would like to auto calculate fields but still allow users to update/edit that field.
Our specific use case is that some conditions allow for this field to be editable, and other conditions will create the auto calculate. Since this functionality does not work we are unable to go live with this portion of the workflow in the application.

Please advise.
Thank you,
Amanda Huber
