Heart rate inaccuracies and inconclusive ECG Charge 5

[LiJaHi]

I just purchased a Charge 5 yesterday. It's my first fitness tracker so still figuring out how it works . I'm concerned that the heart rate measurements when not exercising seem very inaccurate. I've been taking my pulse for comparison and my heart rate feels pretty steady, yet according to the Fitbit it's jumping around all over the place, from 50-90 when just sitting at my computer. It certainly isn't doing that in real life. 

The other issue is the ECG. I've just tried to take one half a dozen times. I watched the instruction video and as far as I can tell am doing it correctly. However, the result comes back as inconclusive each time and when I looked at the chart I can see why - apparently I don't have a heart! It's just showing background noise.

Is the first issue normal and the second one solvable, or did I get a dud Fitbit?

Hi Davide, thanks for responding.

Unfortunately, the Customer Support team only directed to me to read some unhelpful articles that I had already read and didn't actually address the problem of resting heart rate readings being wildly inaccurate and the ECG feature not detecting anything.

Fortunately, Australian consumer law requires that goods must be free of defects and do what they are meant to do, so I was able to return it to the store where I purchased it for a refund.
