Charge 6 heart rate always stops working

[FluffyMuffins]

Hi guys

I have had my charge 6 for two days and constantly through out the day my heart rate stops working and I have to take it off and on for it to read again. As a result I never tracks my sleep and it's getting really annoying as I purchased this to track my bpm and sleep.

Is there anything I can do to fix this?

I have recently changed wrists today as I have tattoos on my other arm and wondered if this effected it 

Thanks in advance

Hello @FluffyMuffins 

Fitbit devices don't do well when worn over tattoos. The ink affects the heart rate sensor functionality.

Now that you've switched wearing your device to your other wrist, it should work better to track your heart rate.

Please keep us updated.
