Below content is an alternative solution for app transfers between Qlik Sense backend and frontend sites. The solution works around two environment limitations.
Slow network write speeds when downloading and uploading apps over Qlik QRS Api
Qlik Sense hardcoded app import folder
The app must be in the import folder for the calling user. To find the import folder, send the following request as the appropriate user:
GET /qrs/app/importfolder
Create symbolic link in the frontend import folder pointing to the network path of backend apps folder.
