Changing Fahrenheit to Celsius on Garmin Lily 2

Hi after reading many of the same questions and responses below and over 1 hour later after trying everything suggested. My watch is still in Fahrenheit. So frustrating as live in the UK. I have tried Statute UK and sync. And tried Metric and then re sync. Still Fahrenheit. 

I have looked at garmin connect app and phone settings.... I think this must be a lily problem. As there is a video which shows you a different garmin watch and it has buttons on the side that allows you to physically set the Celsius in the weather widget..... the lily 2 doesn't have this

 How can I get this sorted as all other measurements are fine?
