I am beyond frustrated

On my second ring pro 2 doorbell in 2 weeks. 2’d one worked for 4 hours and disconnected. Upgraded to a 24 v transformer and I can’t get the doorbell to set up. Right now it’s stuck in set up mode but it won’t let me connect. I’ve gone through the all troubleshooting tips. It spins for a fraction of a second and then pulsates white. No opportunity to connect to the ring wifi. I am livid!
