The spinning white during set up stays solid. I have reset the doorbell by holding button for 20 sec and it goes out and returns to solid white.
When setting up your Video Doorbell Pro for the first time, or after power cycling the device, please allow it some time to power up fully before entering setup mode. After waiting about an hour, try setting up again. Check out also our Help Center article for some great tips on Video Doorbell Pro installation.
