IPS doesn’t currently have this feature, although it has been long requested on the Invision users forum. From what I can work out, the interface with IOS phone is the roadblock. There is a solution for Android but iPS won’t put something in place until such time that both platforms are covered.. so that leaves something like email push notifications for now, if you follow a topic on ozRS you can receive this. I believe you can get these through something like the GMail App. In the meantime we’ll keep on Tapatalk for an update.
