Activities from Zwift does not appear on FR 945

I record activities on Zwift and Zwift transfer them on Garmin connect but the activities are not transfered to the watch and so do not appear on training load. Normally it should work this way for several years since an evolution by garmin.

Why is it not working in my case ?

For information I have the latest firmware on my watch and the watch is configured as primary watch on garmin connect.
