Qlik Sense On-Demand Template App files no longer exist in the app file share, while it is still recognized as an app in Qlik Management Console (QMC).

There may be several reasons for a file to disappear from a folder location, for example;

Accidentally removed by server admin
Incorrectly quarantined by security software
Failed to restore from backup, if system has been restored after disaster
Failed file copy during deployment migration
File not accessible for Qlik Sense service account
