Fitbit Blaze showing temperature icon

[J-flex]

Ok, all you Community legends, moderators, etc. This is just showed up on my watch (Blaze) screen. What the heck?

I’ve never seen this before. What could have caused this. Also, the green lights at the back are no longer flashing.

Welcome, it's great to see you around @J-flex.

I would like to know if you have tried to restart your Blaze? If you haven't, I recommend restarting it by doing the following:

1. Press and hold the back (left) and bottom buttons until you see the Fitbit logo on the screen. This should take less than 10 seconds.
2. Let go of the buttons.

I hope this helps, let me know the outcome.

It took several restarts to get it going again.  Have no clue what caused this.  Fitbit support offered up the suggestion that it could have been extreme cold or heat, informed them that wasn’t the case....no further response...
