Charge 3 not pairing with android device

[Mmo1]

Several times a week my charge 3 will not pair with my android tablet. The tablet will "see" it, but cannot pair. Ut tells me to be sure the charge 3 is in "pairing mode" but I cannot find anything on my Fitbit page that says what that is. Sometimes Myfitnesspal will cause it to sync even when not paired, but that is hit or miss. What does one do? Reboot everything again?

@Mmo1 Welcome! It's great to see you around! 

Let me help you with your Charge 3 not syncing with your tablet and thank you for troubleshooting this issue. Which tablet are you using? Is it compatible? You can try the following:

• Go to your phone's bluetooth settings and remove all devices listed there.
• Restart your phone and restart your device. 
• Check that no battery saving app/feature on your phone is affecting your Fitbit app.
• Also, if you are using an Android device, check that your app has the necessary permissions (settings > apps > Fitbit > permissions) and make sure bluetooth and location services (GPS) are on. 
• You can find additional suggestions here.

Let me know how it goes.
