[Waggy1]

I have reset, unpaired repair.  Do not want to loss 2 weeks of data. Getting error cannot connect due to pin. I am so so frustrated.

Welcome to the Community, @Waggy1.

Can you please provide me a screenshot of the message you are seeing? In the meantime, I recommend taking a look at the help article: Why won't my Fitbit device sync? and follow the instructions provided there.

I hope to hear from you soon and let me know how the troubleshoot goes.

I am not getting messages now. The app will sync and never find anything
and sometimes gives me ! sign. I have rebooted the phone many many times.
I have turned bluetooth off on the phone, restarted it, then turn ed
bluetooth on, then tried sync and nothing. I have tried another phone.

Sometimes the phone cannot find or sometime s it show Charge 3 as available.  Either way it never links or sync.  In the Fitbit app I can get the app to try to sync but NEVER does
