Fenix 5s USB sync fails + (other bugs)

Hello,

I've a Fenix 5s for 40 days, I have issues with synchronizing with the computer for about a week.

Error message in French "Une erreur est survenue lors de la synchronisation avec Garmin Connect."

Should translate into : An error occured while synching with Garmin Connect.

I also had some other bugs that have occured recently :
- screen freezed with a notification popup 2 days ago
- I changed of language from French to English and 12 to 24 hours time display setting. One hour later, the settings were back to French and 12 hour time display

Fenix 5s version 3.30

Garmin Express version 5.5.0.0

What should I do ?
- Should I try to install the latest beta version of the Fenix 5s ?
- Is there a way to see more logs about this error ?

Thank you for your help
  • I have updated my Fenix 5s to 4.10 today and the problem still remains when I try to sync using the computer.

    Garmin Express version 5.5.0.0


    I still have the same error message in French "Une erreur est survenue lors de la synchronisation avec Garmin Connect."


    The sync works over BT but not by USB.

    Even when I removed all the actuvities from the Fenix 5s, it still fail to sync.

    How can I fix this issue ?
