Tactix Charlie activities not synchronized in Explore iOS

I have a Tactix Charlie watch and I recently installed Garmin Explore on my phone to be able to review the activities recorded on my watch, The watch synchronized correctly, all the waypoints, and routes are synchronized and visible in the app but none of the activities recorded by my watch are sent to the phone. I tried it on my iPhone and I get the same result. The activities have been correctly synchronized to my Garmin account and are visible using Garmin Connect web site but not visible in Explore.

thanks for your help
