Hello.  My son's Ace 2 is no longer syncing.  I have tried all tips and suggestions and still no success.  The blue tooth on my phone is not locating it.  Please help.  Thank you.

Welcome to the Fitbit Community, @AmyLR56. 

I am sorry to hear your son's Ace 2 is no longer syncing. Thanks for trying to resolve this and I am here to help. I would like to confirm if you've tried to restart the tracker by following the steps from this help article: How do I restart my Fitbit device? 

After that please turn your phone off and then back on, turn off/on Bluetooth on your phone and confirm if the Ace 2 is paired to your child's account. If it's not paired, please follow these steps: 

1. On the Today tab, tap your profile picture.
2. Tap My Family.
3. Under your child’s name, tap Switch to Kid View.

4. Continue to follow the on-screen instructions to set up your child's tracker. 

You can confirm the steps to set up and sync the Ace 2 tracker in this help article: How do I set up Fitbit Ace devices?

For additional troubleshooting steps, please see this help article: Why can't I set up my Fitbit device?

Let me know how it goes, I'll be around.
