Heart rate stops working when I move

[Naivety]

My heart rate tracker only works when I am sitting still or when I have it on exercise mode. Whenever I have to walk anywhere, even just a few metres, it will stop working for several minutes.

1. I have tried adjusting the strap tightness. 

2. I have moved the watch to several different positions on my wrist. 

3. I have tried restarting the device. 

4. I have tried restarting the device 3 times. 

5. I have already been directed here - https://help.fitbit.com/articles/en_US/Help_article/1582/?q=heart+rate&l=en_US&fs=Search&pn=1 This did not help. 

6. I have tried reinstalling.  

7. I always try turning the heart rate tracking off and on again, it does not help.

@Naivety does it read your HR after several minutes have passed? What value does it show? Also, have you tried wearing it on the other arm - just as a test?

@Marrrmaduke Thanks for your response. Yes I have tried wearing it on both wrists. After a few minutes it will come back with my current heart rate, whatever that is.

@Naivety hmmm weird. I will admit that it happens to me when I remove my watch but that's usually 30 seconds no more than a minute. Have you used Fitbit tracker before? I am asking because the complexion and blood vessels matter here. You obviously exhausted all the troubleshooting steps we could offer here, so the next step would be reaching out to Customer Support. Here's the link to Customer Support page. 😐
