When I click on the ECG app on my iphone4, I get the message "To set up the ECG, openthe Health app on your Iphone." When I do that, I get no message to set up the ECG app. I tried to re-install the ECG app, but it won't let me click on it.
I used to be able to take an ECG with my apple watch 4. Now it wants me to set it up but I follow the instructions and get nowhere. When I try to re-install the ECG app, it won't let me click on it.
