Understanding fitbit app for Charge 3 on Samsung A40

[SunsetRunner]

Hi I have recently bought a Charge 3 and downloaded the app on my Samsung A40.   I receive what I am guessing are messages but don't know how to access them.   They appear as little orange circles with a number in the centre and are attached to the fitbit logo on the phone.   Can anyone help?

Secondly, I am puzzled by the sleep app.   So far at most I have had 5 hours sleep and generally around 1 - 2 hours sleep.   I apparently go to sleep say at 2 a.m. and wake up an hour or so later.   In fact I go to sleep much earlier than that and wake at a reasonable hour in the morning.  So why isn't this recorded.?

Thanks for any help

Hello @SunsetRunner, welcome to the Community Forums!

I appreciate the information and details that were shared in your post. To better assist you and for a better understanding of your question, can you please send me a screenshot of what are you seeing in the Fitbit app? You can check this help article: What’s the new Fitbit app experience? for more information about how to use the app. 

Let me share with you that all of our wrist-based devices automatically detect your sleep, meaning you just need to wear your tracker or watch to bed. Autodetection is based on your movement. When you haven’t moved for about an hour, your device assumes that you’re asleep. Additional data —such as the length of time your movements are indicative of sleep behavior (such as rolling over)— help confirm that you’re asleep.

Also, morning movement tells your tracker that you’re awake. If you’re not moving but not asleep for long periods of time it’s possible for your device to falsely record sleep, in which case you can delete the sleep log from your history. 

Let me know if you have any additional questions, I'll be around.
