Charge 6 / unable to sync / incorrect hour

[Kayak2]

This morning, when I put on my Fitbit charge 6, it was 2 hours behind. I have not traveled or changed anything at all.  My iPhone says it is connected but the app won’t sync.  It is showing the steps, etc..

Hello @Kayak2!  Welcome to the Fitbit Community! It's great to have you here! 

Thank you for sharing the details about your Charge 6 that is not syncing. 

There are some requirements to sync with your app, please verify all and try to sync again: 

•   1- Your phone has the latest version of the Fitbit application installed.
•   2- Your phone has a data connection or Wi-Fi connection.
•   3- Your phone software is up to date.
•   4- The Bluetooth of your phone is activated.
•   5- Your phone is not receiving other Bluetooth signals. (speakers, headphones)
•   6- If you use more than one device to synchronize, make sure that only the one you want to synchronize is nearby.
•   7- The battery charge of your Fitbit device is not too low.
•   8- You do not have available updates on your Charge 6.
•   9- The power saving mode is disabled on your phone. This mode usually causes the device to turn off Bluetooth.
• 10- The Fitbit application is authorized to run in the background on your phone.

Once you have verified the requirements, please restart your Charge 6 and your phone and try syncing again, the sync will correct the time on your Fitbit.

Hello @Kayak2 

Some users have reported that they need to turn both Wi-Fi and Bluetooth off, then back on to get their devices to sync with the app.

Recently, I found that clearing the cache for the Fitbit app on my phone, followed by Force stop has worked for my device to successfully sync with the app. 

Please give these methods a try.

I tried all of these. Nothing worked. I finally had to call in and I received help from an agent.  I basically had to go in to the Fitbit settings and add my phone (even though it was already connected). Not sure why but I highly suspect it had something to do with the I phone update that my phone did the night before.  Issue resolved and btw, the agent was very quick and nice.
