Having all of the above issues. Ecg won't work on active 2. Put my finger there and nothing happens. Tell me all kinds of messages of things to do (which I do,), but same broken issue .
I have my watch 3 updated but the ECG is not in my widgets. I have the blood oxygen now. I downloaded the samsung health monitor app and it says that I have no compatible watch connected. But my wear app shows my watch 3.
