I have not been getting detailed sleep since September 2019. I stopped wearing it to bed since it was pointless. I decided to try again...I reset the Fitbit by pressing button until smile face came on. Charged to 100%, app is up to date and I actually removed and reinstalled th, and the firmware is current. I tried two straps. I still only get simplified sleep so it does know I’m asleep... I see the red light under it is on at night.
looking back at my old data, the last time I had detailed sleep was in August. I’m not sure but it might have been around then that my Fitbit went blank and dead. I was sent a replacement. I don’t think sleep has worked since I got it! I’m guessing it was refurbished and is defective in its programming or something... I have an up to date. Galaxy S9 phone.
any more suggestions?
edit...IT WAS IN SEPTEMBER that I got warranty replacement. I guess they sent me a dud.
