Ring Video Doorbell Pro2

Installed a wired Video Doorbell Pro2.  No issues for about a week and then app showed the doorbell as offline.  When i installed the Pro2 I attached the included Power Kit v3.  I couldn't find the location of the transformer but house is less than 10 yrs old and verified sufficient voltage (19 vac) at the wiring.  The mechanical chime still activates and chimes when pushing the doorbell button but no light indication on the doorbell.  When attempting to factory reset after holding the orange reset button after approx. 5-6 seconds a red circle flashes for about half a sec and then nothing.  If I'm interpreting that correct that's indicating no power but i've still got almost 19 volts at the doorbell itself but it will not reset and still shows as offline in the app.  Last health check recorded in the app shows "power output level 1" and "signal strength RSSI-46".  Not sure where to go to next other then to disconnect the power kit and see if that makes any difference.  Suggestions?
