I remember reading a few months ago that you guys were planning on implementing a “Silent” push notification feature for pub/sub messaging and I was curious if this has been implemented yet. If so is there a tutorial somewhere that discusses how to use this feature?
At the moment it seems that a user can only receive a pub/sub message while the app is active. For my app I need to be able to receive messages while the app is in the background or closed. Using regular push messages would be nice but the inability to unregister a device from a specific channel makes this not an option.
If the “Silent” push messaging feature hasn’t been implemented what is the best practice for a problem like this? The best idea I have so far is to have a background service that executes polling requests every so often which could hurt battery life and cost a lot of api calls.
