ios - How to keep GCKCastSession alive when app goes to background

Question

I'm using latest Google Cast SDK for iOS (version 3.1.1.10003) and our app is remote controlling Google Cast devices, e.g. it changes their volume. It needs to do so also when our app goes to background.

However, GCKSessionManager invokes suspendSessionWithReason: when the app goes to background. This said, the session will be suspended and thus our app can't control it any longer.

How can I make GCKSessionManager not suspend sessions when apps go to background?

Edit: I'm providing a solution below but that is not user friendly due to significant delays when reconnecting.

In the latest Google Cast SDK, you can set it in the options like so:

let criteria = GCKDiscoveryCriteria(applicationID: kGCKDefaultMediaReceiverApplicationID)
var options = GCKCastOptions(discoveryCriteria: criteria)
options.suspendSessionsWhenBackgrounded = false
GCKCastContext.setSharedInstanceWith(options)

However, regardless of that, the session dies from a lost network connection. The trick becomes playing an "empty" audio file from the device, which keeps it alive. Stupid to think that this must be the industry standard.
