Apparently the iOS app has a bug still. I believe Apple still charges big bucks to push updates to an app so that may be why they're taking their sweet time with it. Odd that they wouldn't be jumping to fix something that is specifically mentioned as being a feature of the app. "That makes sense that Apple themselves are the link to the problem. It’s a shame though as the app and Chromecast both say casting is an option. But now it isn’t.
We have other options for TV but the Chromecast is a option we utilize when we can.
