No device found + only ever displayed a single flashing blue light

[YogiFinn]

Good evening,
My recently bought flex2 has only synced once (26th December) and now cannot be found by either my android phone or windows laptop. I have the most current app on both. I have followed all troubleshooting steps and checked the forums. Other than when on charge, my flex2 has only ever displayed 1 flashing blue light. On some posts I have read that this could mean it is faulty. My account is set for it not to receive any notifications from my phone so I am sure it is not that. Many thanks,

Hi @YogiFinn . What phone are you using with your Flex 2? Is it on the Supported Devices List  ?

BLUE FLASHING LIGHT
The possibilities of what the flashing blue light means on your FitBit unit:
POSSIBILITY 1:
Your FitBit unit just needs to be restarted. http://help.fitbit.com/?l=en_US&cu=1&fs=ContactUs
POSSIBILITY 2:  Your FitBit application on your phone needs an update.
Actions to take:
Put the FitBit unit ("pebble") in the charger. Place your phone near the FitBit unit.Open the FitBit app on your phone. On your phone, press whatever sort of Update message is appearing inside the app.  You may have failed to notice the message so far. See if the FitBit unit is still flashing a blue light. If it hasn't changed, put your FitBit unit back in the charger. After a while, see if the blue light on the FitBit unit is still flashing a blue light.
POSSIBILITY 3: Your FitBit unit is defective.  You'll need to contact Customer Support http://help.fitbit.com/articles/en_US/Help_article/1186

Hi, Yes all the devices I have tried are supported. Pebble has been restarted loads of times as with each set up attempt. The app has been updated, reinstalled several times. .. so it does not look like a good outcome! Many thanks.
