You trying to install or update Windows apps on the managed devices and you get an error after app distribution.
If the Windows app to be updated is in use, the installation of the update might fail. Ask the user to close the app and remove it from the background and re-distribute the app update.
If there is not enough disk space on the device where the app is to be installed, the installation might fail. Free some disk space and try again.
While distributing the apps to the device, if there is an issue in the network connectivity, the installation might fail. Check the network connection and try again.
