Got my Venu 3, 3 days ago, and just now opened it and set it up. (I am coming from Vivoactive 3). 2FA is enabled (I did it manually after setting up the Venu 3) and I live in Taiwan. But I still don't see the ECG setup. Any reason why? According to the website, Taiwan is one of the supported regions for ECG. I should mention that although I am in Taiwan, my Garmin connect is set to USA and so is my Garmin Express on my windows laptop.

Any idea what's happening?
