Sense 2 stopped working a couple months ago. Started flashing blue with logo then red X. When I would connect to charger it would work temporarily. Now it does nothing unless connected to charger. The charger is the fitbit charger and it does say 100% charged. I also did a factory reset and that did not work either. This is my second fitbit in 3 years. My first just stopped working completely just after a year. And now this one, which is only around 2 years that I've had it. Don't know if it's user error or if it's a fitbit error. I just want to be able to fix it.
