When I contacted customer service about this, they were friendly and helpful, but ultimately only gave me one extra month free trial, which has since expired and doesn't fix the problem. This is a product flaw. Be aware that if you want this to work properly, you're going to need to sign up for an ongoing subscription. To work as advertised, this is really a $200 doorbell with a $30 yearly subscription fee.
3 - If you do not answer the alert fast enough, you are locked out-- even though someone is standing at your front door. You cannot "turn on" the camera from your phone or tablet. If someone is there and you do not have an "ACCEPT" button on the screen, there is just no way to see or talk to them. This is obviously a software flaw. You should always be able to "wake" a camera remotely and talk to a person at your front door. Or maybe you just want to see the view outside your front door. You should be able to access the camera / microphone and enjoy your front yard.
