MicrosoftI have a couple of updates to add...
There doesn't appear to be a com.microsoft.launcher.next.model.notification.AppNotificationService but there is a com.microsoft.launcher.homescreen.next.model.notification.AppNotificationService
Is it possible that the above guidance (and the docs at MS Learn) won't do anything without the missing "homescreen"?
Little slap from Samsung for those not spending enough:
We had a project team buy hundreds of A8's before any consultation with Tech had taken place. This is the most frustrating news.
This resolved my issue too. Microsoft support struggled with this issue for over a month often pointing the blame on Samsung! Even after showing them this article, they had no clue whatsoever! It worked only after trying this from your comment. Thanks again! Microsoft support had no idea that OEM config policy type is applied as "App Config" to the device and not "Device Config".
