Before the last update they seemed to word flawlessly. I am experiencing the same frustration that so many others are. The app will freeze and indicate bother hearing aids are connected even though the Bluetooth is toggled off in the phone and the hearing aids are both off. This requires uninstalling the app and reinstalling before they will connect again. It usually will not connect to both and when it does within a short time one will drop and it requires reparing. $4000 boat anchors.
