Cannot set up Stick Up Cam

I have 4 Ring devices that connect without issue, including a range booster, but I cannot get the Stick Up Cam to connect. I have had it for months and have tried over and over again but it has never connected. The step that tells me to go into my phone's wifi and connect to the Ring network is where I get hung up, as the network never appears. I ended up buying a Chime Pro this week to extend the wifi for the camera. The Chime Pro connected in minutes, the Ring network appeared on my phone. So I plugged in the camera next to it, and the Chime Pro sees it, but the step that tells me to go into my phone's wifi and look for the Ring network still doesn't work. The network literally appeared an hour ago for the Chime Pro, but not for the camera which is plugged in directly next to it. What is going on here?
