Synchronisation stops

[Rik56]

Every other day my Sense 2 stops synchronisation after it reaches about 80% of the synchronisation process.

This happened on my S23+ but now as well on my S25

When restart my phone the synchronisation works again for a couple of days.

I tried removing the app and reinstalled it after a restart of my phone

I tried to stop my bluetooth and enable bluetooth connections I tried removing my Sense2 from my bluetooth connections

I powered down and restarted my Sense2 

No matter what I try I have to restart my phone to get the synchronisation to finish

 all suggestions are welcome

Good to see you around in the community for the first time @Rik56. 

Thank you for letting me know the difficulty that you are experiencing with your Sense 2 and for the screenshot provided. Thank you for trying to fix it on your own.

Before considering other options, I'd ask you to confirm that you have followed the steps listed in this help article:

Why won't my Fitbit device sync?

Hi

I tried all the mentioned steps several times but  no luck.

Last night it happened again. I disabled the WiFi and Bluetooth on my Samsung S25 phone. Reconnected both.

My Sense2 started to sync but stopped again at about 85%. I kept the screen of my phone on and I decided to wait to see what would happen.

After about 40 minutes the Sense2 finally finished synching.

This happens to me every.single.day.  I have to uninstall/reinstall for a fix.  It's a huge inconvenience but nothing else works.  I pay for Premium and this is unacceptable.  I have tried customer service and got nowhere.

Same thing happens to me! Called CS, 3 days in a row, and go through the same steps each time and after a day it's back to not syncing! Not a solution if you have to reset everyday!!!

My sense2 and phone app usually syncs.  Usually the steps match.  Sometimes the app is ahead of the watch, sometimes vice versa. Occasionally they are synced, but I check it less than an hour later and the app is way behind.  

I have never Uninstalled either the app nor reservation the watch.  But if I do a restart of my phone, then the syncing is Ok again for a day or two.

Same thing happens to me also.  Generally what I do is go to the screen like I'm switching between apps, tap the program name and go to App Info and then hit force stop. Now reopen the app and try to sync. That generally fixes the issue, but for the times it's being stubborn I will force close the app AND clear the program cache and that has always worked.  Never had to do a reinstall following those steps.

I have to uninstall and reinstall the app is the only fix I can get - Please fix this!11!

Hi,

It's not the proper solution, however I tried it several times and it really works well!

It's easier the deleting and reinstalling the app or restart your phone.

Until now it worked all the time.

Thanks for your tip
