Charge 2 not syncing with phone or computer

[Rod_r47]

The app won't work, Can't find fitbit.com, Yes there is a solution:

Restart the phone, Uninstall fitbit reinstall, This solution is not good if the phone has more important uses than fitbit.  

Primitive ideas - I tried force stopped to cure, and guess what i am in!

Just wonder why I get logged out most apps stay logged in. Who would want to steal my steps? Garmin connect seems to do better.  

Software Very recent Android 10, Phone unstressed. Me stressed

Add to that that fitbit connect doesn't sync because it can't find the dongle. which was plugged in.  Reseating it and changing port does not help. And no other options. It sits in the system tray but seems to shut down, Should it not stay resident?

PC Windows 10 up to date. Laptop Unstressed

Fitbit.com says my last sync was 17:20 Yesterday just like it did yesterday.

Browser Chrome

Wonder why all the software is flakey.

Just done the survey

@Rod_r47 It's great to have you here! 

Sorry to hear about your issues syncing your Charge 2 with your phone and computer and thank you for troubleshooting this issue. You can try the following:

1. Go to your phone's bluetooth settings and remove all devices listed there.
2. Restart your phone and restart your device. 
3. Check that no battery saving app/feature on your phone is affecting your Fitbit app.
4. Also, on 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. 
5. You can find troubleshooting instructions for PC and phone here.

Let me know how it goes.
