Import track from fenix 3 watch to Basecamp

Hi there

I am new to this Basecamp thing.  Last week I connected my fenix 3 watch to my computer and saw it in Basecamp.  I could see the tracks of the runs I did with my watch.  I could then import the tracks in basecamp and save them.  Not I didnt change anything really, maybe an update somewhere, but when I connect my watch to my computer Basecamp stil sees it but its like there is nothing on it.  I tried several times, restarted it, but no luck.

Anyone has an idea what could cause this?

Basecamp 4.8.11

Mac OS Big Sur 11.2.3

Thanks
