why does syncing Epix Pro with Connect require internet

This fall I was hiking in the Peruvian Andes, a region without any internet connection, for almost two weeks. Recharging watch and phone via PV cells was possible, but unfortunately I could not access my daily hike statistics (distance, heights, route...) in Garmin connect on my phone due to the lack of internet. For days... This was quite inconvenient - and I was and still am asking myself why it's not possible to do this kind of syncing via Bluetooth. It would be a most welcome improvement - or did I miss something?

Thanks!
