Spotlight Cam Plus Not working

This is a brand new camera, I bought 2 of them on Ring website. Try to set up the device following the app instructions, at one point it says:"Connect your Spotlight Cam to a power outlet - Be sure to use a RingIndor/outdoor power adapter with a USB-C plug. Then wait 30seconds for your sportlight cam to turn on."A the bottom there is a button that says "Sportlight cam is on"I waited the 30 seconds with no luck. Also I try to battery power it (ring batteries fully charged), still not working. I wued the power adapter from the other camera, still not working. I also try to push the button on top of it. Still not working. What I can do next? Any idea? Thanks
