Sleep-tracker deleted datas

[Filosofalbo]

Good morning everyone!
I started using the sleep recording app about three weeks ago.
Everything was fine until I noticed that many days where I'm sure I'd started the app were now missing from my data history.
With the app, I discovered that, instead of talking, I moan a lot during sleep, almost as if I were being beaten.
The fact that some recordings are missing worries me, and if I need to change app, I need to know it now because I think it's important to investigate this problem I've discovered I'm having.
Reading the forum, I discovered that this problem has already been reported in relation to a time zone, which is why I'm writing from Italy.
Can anyone help me?
Thank you very much <3.

Hello @Filosofalbo 

I noticed that you mention that you "started the app". Are you using a Fitbit device or only the Fitbit app to track your sleep? If you're only using the Fitbit app, that could be the problem. I don't recall seeing that the Fitbit app can track sleep without the use of a Fitbit device. 

You might want to review the information on this help page (<-- click) which explains how Fitbit tracks sleep.

Hi RiekoC! Firstly, thank you for your kind reply!
No, i don't use a Fitbit device, just the app, and it keeps tracks just by recording sounds while i sleep, it hasn't ever given any problem till this 😞

Hello @Filosofalbo 

Thank you for clarifying that you're not using a Fitbit device, only the Fitbit app. 

I'm not sure what to suggest since I'm not familiar with using only the Fitbit app to track sleep. Hopefully, another Product Expert or user who has used the app in this manner might chime in with suggestions.
