Dear Support team,
https://developer.amazon.com/docs/dash/notification-messages.html
In this reference, such a description was mentioned. "Which device models will use the new notifications?" In the case of I request existing device models, I understand that new subscribing devices will be v2.0 notifications.
<Question>
Will already subscribed devices (already runnning devices) migtate to v2.0 notifications too?
