How do I restart Charge 3?

[multiverse]

So many problems with syncing and sleep tracking!  Spent hours on Christmas fiddling with this well-marketed bracelet, just like when I got my Ionic a year earlier. 

Many posts say to restart and wait for the smiley face `r=<:..  I see no smiley face at any point, neither on my charge 3 nor on my own face!  How do you actually restart this thing?  If it has been restarting all 100 times I've tried, it hasn't fixed a **ahem** thing.

Hi,
First I called the help line, I found the number on my dashboard then the tech told me I had to take a picture of my Fitbit face to prove it wasn’t working, they sent me a link to send the picture to and they sent me a new face!
Hope this helps!

They couldn’t tell me that themselves when I called them for help?
Apparently not, because the only help option was for me to order a new
device and I would get 25% off. I don’t want 25% off. I want a replacement
that works for once.
