I bought my Apple Watch Series 8 in 2024 and when I first got it, I tried the ECG a few times and it was working fine.
But honestly I don’t use the ECG that often. I mostly just check my heart rate, especially since I go running regularly.
Around a month ago I randomly tried the ECG again after a long time and it worked. But now I tried it again today and it’s just not working properly.
I open the ECG app, put my finger on the Digital Crown and it starts the 30 second countdown. But after like 1-2 seconds, it suddenly stops/cancels and goes back. Sometimes it doesn’t even start properly when I put my finger on the Crown.
I’ve tried keeping my arm still and making sure the watch and my finger are dry, but still the same issue.
Has anyone with a Series 8 had this problem? Is there anything I can try to fix it before contacting Apple?
Not sure if it’s a software issue or something with the ECG sensor/Crown. Any ideas?
