For some reason on iOS 15 the app icon banner is missing for the expanded view on rich notifications. Toggling UNNotificationExtensionDefaultContentHidden back to false on the Content Extensions Info.plist causes the app icon to come back, but this isn't what we want since it also shows the original title & message.
I've noticed that the Facebook notifications also have the same issues at the moment.
I couldn't any documentation on why this changed.
Attached is an example of a sample project where the App Icon is missing.
