Any Administrator Read Only Questions needs to be hidden
If any changes are made to questions in a form and those questions are made "Administrator Read Only", they are still visible when reviewing submitted follow ups. For example, our grant report follow ups were a copy of the previous year. Many of the questions had changed or were no longer applicable to grantees. However, some of the grantees had already submitted a report in that process. Once the report has been submitted the questions made "Administrator Read Only" still show up and make it very hard to evaluate a follow up form. It looks messy and makes the process not very easy on the administrator side. Once questions are made Administrator read only, they should only be visible in the process manager and not submitted follow ups.
For question on the Organization and user form that foundant control we have a question visibility of “Hidden” it feels like this would be helpful in your scenario.
Let me know if you have thoughts.
