New Responsive Forms in AppStudio
The New Responsive Forms are currently not supported within Nintex AppStudio. This means that we loose the new functionality developed for New Responsive Forms - signature panel especially.
Currently only .XML and .nfp forms are allowed.

Currently, App Studio only filters on NFP and XML. Universal forms export as JSON from O365. Would definitely need to add the filtering to App Studio.
