As is listed here, my device stopped working. Health check said power was good, but devise was not responsive and Pressing the side, "reset" button did not have any effect. Customer support had me hold the reset button down for 20 seconds and it did not revive the unit. I then did my own trial, and applied the iPhone type reset- By pressing and holding the Side Reset button AND the doorbell button at the same time, for 20 seconds, my Ring Doorbell came back to life! All good.
I have this exact situation with a slow walking white light rather than a spinning white light. Did you eventually resolve your issue?
