Automatic VPP License Assignment for iOS/iPadOS BYOD

What
Device-based VPP license assignment is the preferred method for managed iOS and iPadOS devices because it does not depend on a user's Apple Account. BYOD enrollment cannot use device-based assignment, however, and some content such as Apple Books requires user assignment. FileWave's Automatic setting handles both cases: it uses device-based assignment when the device and content support it, then falls back to user-based assignment when they do not.
When/Why
A VPP app association can assign its license to the device or the user. The VPP preference sets the default for new associations, while the license setting on an individual association can override that default. Select Automatic in Preferences when you want new associations to choose the compatible assignment method. The preference is shown below.
You can override that default on an individual association:
Automatic first tries device-based licensing. If the device or content cannot use that method, FileWave uses user-based assignment instead. The fallback still needs a FileWave user and VPP user association that can receive the license; Automatic changes the assignment method, not the user identity behind it.
Automatic assignment also helps when you do not manage BYOD devices. Apps that support device-based licensing continue to use it. If you later associate an app that lacks device-based licensing or an Apple Book that requires a user, FileWave can use user assignment for that association without forcing you to remember a one-off setting change.
How
Changing the preference affects new associations. Existing associations keep their current license setting. If a BYOD device receives a device-based association, the app can be associated but cannot install because that enrollment cannot use device-based licensing. Update applicable older associations to Automatic so FileWave can fall back to user assignment.
If many existing associations need the same change, use the Associations view to edit them in bulk.
