Applications that only can be updated, when the app is not opened and it is not possible to close the app during normal business hours. The users are mor like frontline workers and they do not care about the apps and the computer so they would not understand, why they should go to the company portal to update the app. So I would need to do a required deployment, but this also can not be installed during business hours, even when the device was turned off for 3 weeks during vacation.
