Syncing Garmin Coach Plans

Hi,

do garmin coach plans sync in the Edge via bluetooth connection to the phone and no other way?
I created new garmin coach plans for myself, they are visible on the web (one week only), they are visible on the phone (also one week only), but they are not visible at all in the Edge even after manually force wifi sync, when I click on garmin coach plans it says that it need to connect via bluetooth with my phone and indeed only then did my plan show up. Why is it not possible to sync this via wifi, do you plan to change this in the future because I do not connect my phone to the Edge via bluetooth?

Firmware 25.25

Thank you.
