Ring Doorbell Not Working Firmware Issue ?

I have a new Ring Doorbell which is not playing ball. It is connected to our wi-fi and available in the app but is not functioning. The device is stuck in an endless loop flashing white and then blue and then white, blue without end. I also cannot connect to a video stream. Device health reports are also showing the device is okay but some of the details are wrong (showing hardwired or solar powered when it is not). It is not an issue on the wi-fi as this is a second Ring Doorbell at home. It is also not a wi-fi coverage issue either. To be sure I switched off any port filtering with no joy. I must have reset the device and started from scratch 10 plus times. Same result each time. Any ideas before it gets returned ?
