Modifying or Deleting Notifications after You Share Them

Do not modify a notification once it has subscribers. Instead, create a new notification and delete the old one. If a user has subscribed and a notification is changed, the inputs may change and the subscription input overrides may no longer be correct, which can cause the user to no longer receive notifications without realizing why. On the other hand, if a notification is deleted, when a user goes into Subscription Manager, he will see an indication that the subscription has an issue.
