Can't Connect Ring Peephole Camera with PC or Tablet?

I've tried several times to connect my Ring Peehole Cam to a PC or Tablet, and neither will connect. I've downloaded the Ring app, and when I click on "Set Up Device" it takes me to a page with instructions on how to set up a camera. I follow the instructions, and it always takes me back to the instructions page and can't get passed that. My Amazon Echo Show won't connect with Ring either.
