ECG fails after 5 seconds

How fix problems ? Can not read bpm. 5 sec will jump out. Some time no response for long time. I reset 5 time can't fix it.

It may be the strap on the new watch. It fits different than the GW3.

I understand how frustrating this can be. For concerns regarding the ECG feature, you will need to reach out to the ECG team by calling 1-855-795-0509, option 6. I apologize for any inconvenience.
