Ring Doorbell no longer connected to phone

Ring doorbell was installed months ago. Today when trying to start live video, I was required to set up an account. Then it wanted me to connect device with QR code. There is no QR Code. There is no PIN. The connection instructions in the app say press the orange button on the back of the device. It is already installed on the doorbell. Do I need to remove it as if I were installing it for the first time?
