ace 2 will sync but wont update or connect

[Kerrz]

hello, 

I have recently bought a fit bit Inspire 2 which I connected successfully with my Chromebook, I got my children the Ace 2 for Christmas to use on my family account, it says that it has synced but it will not update or connect. 
I have tried making sure my battery is at 50%, turning on and off my Bluetooth and nothing, I have just read that Fitbit does not work with the chrome book but I had no problem with my Inspire 2.

kind regards, Kerry

 here is something a moderator posted about phones being compatible:

"Please note that your phone or tablet is not on our list of compatible devices. We confirmed that the devices on this list are fully compatible with all features of Fitbit devices and the Fitbit app. While a phone or tablet may not be verified as fully compatible, the Fitbit app may still work with your device. 

We routinely test new devices to ensure full compatibility with Fitbit devices and the Fitbit app, and are constantly working to confirm compatibility with new phone models. Be sure to verify that your phone or tablet meets the minimum operating system requirements.

If your phone supports Bluetooth 4.0, we provide assistance and troubleshooting steps. Because your phone or tablet is not fully compatible with Fitbit devices, we can't guarantee syncing and other Fitbit features. "
