@nikclayton Bookmarking this to try after I get back from my vacation, thanks.

However, one thing in the linked article seems wrong to me. It shouldn't be necessary to make the application's battery settings "Unrestricted". In fact, that's the big selling point of push notifications, that there's only one app periodically waking up and checking, thus saving battery by only having one network connection active, and that app will wake up other apps as notifications for them come in.
