I have a form with a question that should only be editable when another question has a certain value. Using Survey123 Connect, I entered an expression in the question's readonly column, and that works in the Field App, but when viewed in a web browser, the question is still editable. I haven't been able to find any documentation saying that it isn't supported. Has anyone been able to get this to work?
The web app does not support dynamic read-only questions at the moment. We do have an existing enhancement related to adding this capability and I will add your request to it and/or will look to add documentation related to the limitation in the web app.
I am experiencing the same issue. I spent quite a bit of time hinging my development on this feature based on the form view in ArcGIS Survey123 Connect only to find out it isn't supported in the browser. Hopefully this feature get's implemented. For now I'm going to have to create a second form for the same feature layer.
