Quite likely a stupid question but does the ECG function work via an app? Just wondering if it’s possible to access it by changing your Apple ID region/country setting on the Watch and using a VPN - i.e. similar to the approach used to download and run, say, BBC iPlayer on Apple TV and iPad?
Based on location of purpose I believe, which can then be unlocked by future software updates (like a few European countries I believe)
I have a series 4 purchased in America and the ecg app has worked since it first came in, even though I’m signed into my NZ Apple account.
I have just googled all this and it appears that there is a small amount of rigmarole involved but the key point is first registering a capable Watch in a country that is ECG App eligible.
