ECG in watch not available in my region
I have a new Apple watch 7. Now I want to use it to measure my ECG. When I want to open the function in the health app on my iPhone, I get an message "The ECG app is not available in your region". My region is set to Austria, now I live in China. Both countries should be OK according to watchOS - Feature Availability - Apple
How to fix this?
