Sync nightmares

[Safranit]

I have a new Charge 3.  I bought it in the US and it synched just fine to my Moto G6.  (Both with my parent's WIFI and the hotel WIFI where I was staying)

I am now home in Israel.  It will not sync using my home WIFI, and using data (which is not my preference) doesn't work regularly.  

I have tried everything suggested... starting and stopping the app, logged out.. (BTW, it won't even let me log into the app with WIFI only).

Suggestions?

On the charge 3 there's a reset button under settings, about, scroll down to clear user data, click on that to click the check that allows the watch to reset.  You'll have to Re-connect your Bluetooth connection and the notification settings on the Fitbit app. Hope this helps! I did not lose any data through this process except the days when my phone wasn't syncing.

On the charge 3 watch itself there's a reset button under settings, about, scroll down to clear user data, click on that to click the check that allows the watch to reset.  You'll have to Re-connect your Bluetooth connection and the notification settings on the Fitbit app. Hope this helps!
