responsive external form
Due to the Sharepoint is now 2019, they go much more trendy design on layout design. However Nintex only allow to publish a classic form as a external form. It is quite not feasible to maintain a single design not only for the public SharePoint of a Website.
We think the Responsive External Form is a must in the future release.
