I'm creating an app in which users can subscribe to multiple channels, and certain users can send notifications to multiple channels. This is set up through ACS Cloud. If a user is subscribed to channel A and channel B, and tan identical notification is sent to both channelA and channelB, the user will receive the notification twice. Instead of sending the same notification to multiple channels, is there a way to send a notification to an array/list of channels, or set it up so the user doesn't receive the notification twice? Currently I am using some really dodgy logic based upon the content of the notification and time of the notification to filter these out.
Thanks for your help
