fenix5 - no data in garmin connect

Hi together !

with my fenix 5 I've a problem. It shows me on my watch all my steps and floors, my pulse and so on :-)
Then we I connect it with my iPhone app Garmin connect - nothing will be displayed. Also not, when I connect my watch direct via cable to garmin connect.

It always sync - but afterwards there are no datas available (also no sleep information).

Any ideas from your side ? I had all these information at the beginning with my new watch. Perhaps I've miss-configurated something ?

Thank you all
Alfonso
