Syncing issue after updating Fitbit app

[DesDe]

I updated Fitbit to version 3.37.1.  Sync is still not working consistently, in fact it does not work more often than it does work.  My Android version is VS98739c, which shows as the current version with no updates available.

Hello @DesDe, it's nice to see you again participating here in the Community Forums.

Thanks for bringing this to our attention and for the details that were shared on your post. I recommend you to check how the syncing procedure works here and see if there's a missing requirement on your mobile device that's preventing the syncing procedure to be completed. Then, you can move forward and try the troubleshooting steps that are specified on: Why won't my Fitbit device sync? and let me know how it goes. 

Let me know if further assistance is needed and if you have any additional questions.
