There is no available update for a third-party application
Do you have a third-party application that can be assured needs an update, but Automox cannot see it?
Microsoft Visual Studio has an available update, but it's not appearing on the Device Details page as needing an update, or it cannot find the latest update available.
Check to see if the software is listed on the Third-Party Software Supported page. If it's not there, then the only way to update the application would be to use a Required Software Policy or a Worklet.
