Sleep and step accuracy using Flex 2 pendant

[Louise14]

5 days ago I switched my flex holder my wrist to the necklace holder.since then it has stopped tracking my sleep and appears to be tracking only part of my steps. Any advice?

Hi @Louise14, welcome to the Community Forums!

Thanks for bringing this to my attention. If you wear your device in a loose-fitting accessory such as a bangle or pendant, you may see a slightly different step count than if you wear a classic wristband. During workouts and sleep, we recommend wearing the classic wristband. Make sure the wristband fits securely but isn't too tight. 

Let me know if you have any additional questions.

For sleep tracking, your tracker needs to see your bodies movement through out the night. Wearing the tracker on a chain means the tracker may be laying on the mattress.
