Hi! I could be missing something here, but in the docs for getNotificationCategoriesWithCompletionHandler , it states: categories The set of UNNotificationCategory objects containing your registered notification types. If your app has not yet registered any categories, this parameter is an empty set. But if I haven't set any categories yet, the categories parameter is NULL, not an empty set. Not sure if this is possible docs bug or implementation bug

hi! Was hoping to be able to modify a notification's associated ID inside of UNNotificationServiceExtension, but it seems like it's not possible since the contentHandler only accepts type UNNotificationContent (not UNNotificationRequest). (docs here - https://developer.apple.com/documentation/usernotifications/unnotificationserviceextension/1648229-didreceivenotificationrequest?language=objc) Thought it was worth a shot posting to see if anyone had found some workarounds to this, thanks!
