Understanding?

I just installed a Ring door bell to the breezeway door, and have a couple of questions.1. When I ring the doorbell or go near the door, I get a signal on my cell hone but the chimes on the wall in the living room does not ring. Can't I have the house chimes sounding also?2. If I add a 2nd doorbell to another door, do I have to go thru the whole set up again? Hoping that they both work with the same app I already installed on the phone.
