Charge 2 won't sync with my Samsung 8

[Jmoore2]

My Charge 2 hasn't synced with my phone since January 10th. How can I get them to sync?

The usual things to try when you get syncing issues are:

• restart phone
• restart fitbit using this procedure: https://help.fitbit.com/articles/en_US/Help_article/1186/
• restart fitbit a few more times (it doesn't always work)
• "forget" the fitbit in the phone's bluetooth settings
• go through fitbit's troubleshooting guide at: https://help.fitbit.com/articles/en_US/Help_article/1866/
• if none of that works then contact customer support: contact.fitbit.com

My Charge 3 hasn't synced with my Samung 8 since the 4th January. Tried everything suggested in the previous reply and still not working. What an expensive waste of money this watch is.

I got a tip that I could turn off the wifi on my phone and use only mobildata (4G). That works. Only way that I can sync.  But I don't know why... It's extremly irritating!! I have tried everything but wifi is not working with the Fitbit app. My troubles started yesterday. When I opend the App it asked me to log in. I could not even log in, before I used mobildata and not wifi...
