Video Door Bell Pro - Over Voltage Ring Transformer

I have 5 Ring devices and a current Protect Plus annual plan. My devices are: 1 \> Video Doorbell 1 - 5 years old still going strong 2 \> Spotlight CAM - 2018 3&4 \> 2 off, Stick Up CAMS - 2019 and 2020 5\>Video Door Bell Pro - Chime Pro Kit - June 2018 My problem is Item 5, which has crashed. I have tried everything advised by Ring but got nowhere. There a no lights, and it does not connect to any network (Chime Pro or WiFi). I rebooted my WiFi router twice. All other devices on my WiFi are working fine. I have checked for power on the rear of the Video Door Bell Pro AC power is there. I have checked the device specs which state…. 16-24 VAC, 40VA max, 50/60Hz. A large Ring transformer came in the box. The Ring Transformer shows on its label max output 24VAC. HOWEVER, this Ring transformer is delivering 27 VAC RMS (which is 34VAC peak). The excessive voltage explains the short life of the Video Door Bell Pro that I purchased. Please note I am a Chartered Electrical and Electronic engineer. I have gone well beyond the average user to check this Ring Video Door Bell Pro device. HOWEVER, this Ring transformer is delivering 27 VAC RMS (which is 34VAC peak). The transformer is a simple device, and it could not suddenly deliver 12%-40% overvoltage. It is, therefore, reasonable to assume that the Video Door Bell was over-voltage and stressed since the day of installation. The conclusion is the Video Door Bell Pro has expired early in its life due to sustained over-voltage. It is not typical for Ring Devices which have a good reliability reputation. Feel free to refer these comments to your technical team. If they wish they can examine the Video Door Bell Pro and the Ring Transformer. I trust you can help resolve this problem as soon as possible. Many thanks WHO CAN I CONTACT FOR RING SUPPORT IN AUSTRALIA
