When an application is uploaded into Qlik Sense SaaS, all sheets are placed under "My sheets", regardless of their previous state. Each must be made public manually and individually as needed which can be tedious, especially when uploading many apps. Worse, it may be that the user does not notice, and then no sheets are visible to other users.
The suggestion is to add a check box in the "upload app" dialog titled "Make sheets public" to simplify this process.
