When Apple publishes a major OS update, a small number of users may find their device management solution stops working. In most cases, it’s not really a problem at all, just a licensing condition that needs to be resolved.
Make a diary date for T&Cs and other settings
Apple frequently requests its customers approve new terms and conditions (T&Cs) when major OS updates roll out. You probably needed to accept new T&Cs when you upgraded to iOS 16 or macOS Ventura.
The problem for managed device fleets is that if these aren’t approved, certain features may stop functioning. Fortunately, you can easily get your systems working again in Apple Business Manager.
