My FitBit Blaze hasn't been tracking sleep for the past week and recently my heart rate tracker has been stuck as 70, or N/A during workouts.
I've performed a manual shutdown through the device settings multiple times which unfortunately doesn't seem to fix the problem. As a bonus, a hard restart by holding down the left and bottom right buttons doesn't do anything. I've seen people say you need to hold them down for anything from 10-30 seconds...I've held them down for 2-5 minutes for periods and yet still no restart. I've had to go back to using an old fitness tracker by a different brand. Very disappointed that it seems like my Blaze is toast as most people I've spoken to have moved on to Whoop after similar issues.
