title: Push Notifcations working but connectToFcm() is not defined
body: <p>My push notifications are working (albeit a bit buggy: PNs while in foreground cause the app to crash) - I'm receiving a notification on my device, but in AppDelegate > tokenRefreshNotification() "connectToFcm()" is unresolved and had to comment it out. Where is that method defined? I'm apparently missing something.</p>
