Issue syncing Multiple devices - Flex 2 steps shown in challenge but not on dashboard

[DMDG_868]

I have a charge 3 and Flex 2 connected to my app,   on Monday I used the flex 2 for a few hours and registered over 10,000 steps. I switched to my charge 3 later in the day and registered another 15,000 steps. My weekly challenged used the steps from my Flex 2 but not the charge 3 for that day and my dashboard only shows the charge 3 steps. 

I did sync at the end of the day,  and have been syncing ever since but the number of steps for Monday hasn't increased.  I'd appreciate any assistance to rectify this issue.

Did you sync before switching from Flex 2 to Charge 3?  You should always sync right before switching.  Otherwise the Flex 2 data is just on your tracker and hasn't gotten to the Fitbit database.

Unfortunately, I didn't sync before switching. 

Is there anyway to now get the data from the flex 2 to show up? There is a gap in the graph where it should be

I'm not sure.  I suggest sync with other device, then switch back to Flex 2 and sync with it - but not sure if that will fix it.
