Ionic tracked sleep in two parts

[SLD1875]

After updating my ionic this week my sleep tracker now splits my sleep in to 2 parts. 

It used to track from 12.30 am up until roughly 8am , it told me when I was awake, restless , deep sleep, which was great and all worked fine. Since the update

it now tracks in 2 separate cycles

eg 1.30am to 3.20am

then I disappear for 2hrs

then tracks again from 5.20 am to 8am.

it then states as I didn’t have 3hrs consecutive sleep it can’t give me an accurate reading,

this has happened for the last 3/4 nights.

i have tried setting my sleep time on App from 12.30 to 8, but still records 2 separate logs and I go missing for a couple pimple I of hours during night?

@SLD1875 A warm welcome to the Community. Sorry for the delayed reply. 

Thanks for letting me know that your sleep splitted in two parts. I would like you to restart your Ionic and make sure you're wearing it higher on your wrist (about 2-3 fingers widths above your wrist bone), the band should feel secure but not too tight. 

Keep me posted!
