Cannot connect to WiFi (stops spinning)

I cannot connect my Video Doorbell Pro to WiFi. When I attempt to set it up, the white ring starts spinning, but as I wait for a "Ring" WiFi network to appear (it never does), the ring stops spinning. Hence, I can never connect my phone to the doorbell to get it configured.I remember when I first set this up, it was a bit finicky, but I initially got it working. It broken quite a while ago, and I didn't get around to re-attempting the setup until now (couldn't find the T6 bit!). I'd like to get it working again, but this is obviously an obstactle.
