App stopped syncing 9/7/25. I've spent hours and nothing worked

App stopped syncing 9/7/25. 

The only thing I haven't tried is a factory reset. I'm disabled with a neurological illness. This Charge 6 which I used to track sleep, is making me cry in frustration.

Anyway, this doesn't work because it doesn't exist:    Navigate to Settings > About > Factory Reset on your Charge 6. 

Device has claimed I need to "Add card to wallet" despite the fact that I paid $79.99 on 8/16 for Premium. AND, device shows phone icon with slash through it, even though I JUST paired it a minute ago.

@Chiparella , a warm welcome to the Community! Thank you for your efforts.

I get where your frustration comes from, but be assured that we're here to help you further. 

Could you please describe what you've already tried, so that I don't ask you to repeat any steps if not necessary?
If you haven't done so yet, please have a look at this:  Why won't my Fitbit device sync?

Please make sure that you have the latest Fitbit app installed. 

 Factory Reset on the Charge 6 is called "Clear user data". Please be aware that this will delete all the info on your Charge 6 and this cannot be recovered afterwards.

I have the same issue, nothing I do seems to work. I deleted the watch from the app and it wont let me add it back. It keeps saying something went wrong

@RAMalcolm , Thank you for your message. Welcome to the Community.

Does this happened with Wifi or with mobile data?

Could you please describe what you already tried so that I don't ask you to perform them again, if not necessary. 
Did you try the steps and tips described here?
