Please check a signature of your applications. You’re not able to upgrade an application if a signature is not matched even though their package names are same. You can see more details here: (https://support.samsungknox.com/hc/en-us/articles/360037312194-New-Features-in-the-KC-KCS-1-26-Release-October-23rd-2019
I try to upgrade an application already installed in device using KC. While a new version of application is being installed in device after a new profile with a new app is assigned, an error occurs. I don’t know what’s wrong.
