Loss of sleep data

[JimZ1858]

After manually adding data to my sleep track my Fitbit Ionic lost about an hour plus of data that had previously been accepted and staged. Anyone notice this with IPhone 9?

Mine stopped logging sleep after about a month on my Samsung S8, got a new S10 in March and still no logging. In mid April my Ionic experienced the same catastrophic failure that so, so, so many people have been reporting on this site and the replacement is, once again tracking my sleep. The life span of these things seems to be about 3-6 months average.

A warm welcome to the Community @JimZ1858. If you tracked your sleep and then you manually logged it, the data will be overridden and it might show you less sleep hours.

If you noticed that your Ionic didn't track your sleep properly, you will need to delete the one that you already have in your account and then manually log it. I would like you to delete the sleep log that you previously had and log it again. 

It's great to see you around @Irishwolf66. Thanks for sharing your experience with us, I hope that you can continue enjoying your watch. 

I'll be around if you need further assistance.
