Ring 2 and mechanical chime

Hi all,I have just installed my Ring 2.I checked my existing Mech Chime and it is in the list of compatible devices. it is a Legrand 41243.The ring 2 is installed and all working with the app nicely.My issue is that the ring 2 is not ringing the mechanical chime, yet its supported.The Chime has a built in transformer - 230V-14V-55o/BIs this transformer too under power?Any assistance is greatly appreciated.Regards
