I think there is some kind of automatic sync ONLY with the app.
As you can see in this video approx. at 3:00

On approx. 7:20 the guy is using another folder....
Another point would be an mobile app for Android or iOS, but there is no one...
I currently thinking of canceling my preorder and wait for further updates.
