Ring Doorbell Setup Failure

Hello,I've gotten a hand-me-down doorbell from a friend. I've reset it, and tried to set it up, but it keeps failing after inputting the Wifi Password. My other devices don't have any trouble connecting to the network.Sometime a page appears in the app while the doorbell's LED is still spinning white with a diagnostics page (to selecting from which side the led flashing is coming from) while the doorbell keeps spinning in white, and other times, the spinning will stop before that page appears.Any ideas? Thanks.
