• Firewall
• The customer uses "download-only" action in Dynamic Updates for Content Update.
• The Content(App) version on Panorama is higher than the Content(App+Threat) version on Firewall. 

• When "download-only" option is used under the schedule for dynamic updates, the newer application versions will not get installed.
• It happens when the Content (App version) on the Panorama is higher than the Firewalls Content (App+Threat) version and Panorama is pushing a config with reference to a new application ID like security policy etc.
• The Firewall will not understand this new App-ID and hence the commit will fail. 
• In this sample, app-version never updated from 769-4439.
