Had an issue since day 1 with this,
tried to uninstall, reinstall.
the doorbell rings, notifies the app and the ringer indoors, can hear the person outside but cant talk back. and to confirm it is the outside speaker, if you push the doorbell the light goes blue but you dont hear the ding dong that you usually get from the device.
i have 2 other devices and they all work fine but not this one
