Live view doesn't work

I purchased two ring doorbells back in October and they worked fine for awhile. We moved, but kept the same Router, same ISP, same speeds, and now live view doesn't work and the motion detection seems to refuse to acknowledge any changes we make to it (it goes off every time a car goes by).I tried calling Support and, despite being told this would absolutely work, none of the walkthroughs worked. I own these for safety and the fact that I can't see what might be triggering the motion sensor or what's making my dog bark is not worth the $200+ I paid.
