Fenix 6X not recognised on Big Sur 11.2.1

Can I get the same Basecamp support on a Mac (Big Sur) and a PC running Windows 10?

On the MAC the Fenix is not detected on Basecamp 4.8.11. It's working fine on Express.

I have just updated to BigSur 11.2.1 and I don't remember if it was working on BaseCamp before the update.

With the pandemia I did not create any track lately for my Fenix on BaseCamp..

As i work around I'm using Explore to upload track's on the Fenix....

I know it's not a matter of privacy setting my 1030plus is working fine on BaseCamp.

Your help will be appreciated?
