Blaze won't sync after firmware update

[hpedolzky]

i get a message:

Bluetooth issues. if you see this message for the first time, press "Cancel" and try again. If you continue getting this message press "Restart Bluetooth" to turn Bluetooth off and on. I tried to reset Bluetooth several times, deleted the app on the phone and re-installed. turned Bluetooth on the phone on and off several times. The watch is working and keeps track of my activities, but is 14 minutes late than the actual time

Version Number 17.8.402.1

Hello there @hpedolzky! I'm sorry for the late response. Thanks for already troubleshooting the syncing difficulties you're having with your Blaze. 

While reading your post I was wondering if the mobile device you're syncing with is included in our list of supported devices? You can see the list at: Which phones and tablets can I use with my Fitbit watch or tracker?

Please keep in mind that when a device is not supported we cannot guarantee its functionality with the Fitbit app. It might work at a certain time and then it can stop working out of nowhere after an update. This is because the app is not optimized to that device and any change could impact the performance. 

If your device is compatible, but the issue persists. In order to solve this, please go to the Bluetooth settings on your phone and remove the tracker. In the list of Bluetooth devices you'll see the Charge 3 and next to it, this symbol "!". Hit the symbol and it will take you to the next step, once you're there select the option that says "Forget this device" or "Unpair".
