longterm issues with syncing

[madaA]

I have huge troubles to sync my fitbit.

It was sitting in the box for years and now i am using it since like october.

More often than not it takes days to get one sync.

I used all advice i found here (continuous sync enabled, enable location services, no battery or app restrictions, resetting, etc).

I tried to make it work with two different mobile phones, win10 notebook.

Nothing seems to helps. Fitbit just decides to not sync with any device for random period of time. Which makes device useless for me, i need day to day data, that is reason why i bought it. Huge dissapointment.

Is there anything to be done?

Hello,

thank you for answer.

Yep i followed all  the steps from article.

Sometimes it helps, sometimes there are days my fitbit won't connect to any device no matter what i do (resets, reinstalls etc).

Since 3rd april my fitbit haven't sinced yet. No luck with mobile or windows app, tried to (again) restart device, reinstall apps etc...

Any recommendation how to proceed?
