whether there is a mechanism that repair damaged applications?
In the QlikView is a mechanism recovery applications to retrieve only the script download, no data model, with or without visualization. In the Sense there is some kind of mechanism? Fully rely on the backup application?
At this point there is no mechanism to open only the script in Qlik Sense. For now you will need to fully rely on backups. I do know that this is being looked at as a future feature but there is no timeline as of yet.
