That is custom functionality that has been created by a developer. You should reach out to whoever built this functionality if its not working as expected.
You say custom functionality but it is part of the Umbraco documentation rather than a third party. Are you suggesting raising it with Umbraco developers?
Yes I followed documentation. The forms work fine, not the paging or summary.
I don’t see anything in the standard Themes/default/Form.cshtml (that comes with the installation) that contains logic to display either and if that was the case then what would the point be in having the appsettings for it?
