@Adrian-Avram, It does. If the upload did not work, you will see a small up-arrow in the profile icon, until it resolves itself.
One problem though, which I experienced myself last week, is the addition of extra pictures. The ones you did not take with the built in camera app, but decide to pick from your own gallery. That seems to only work if you do that just before uploading. All pictures I attached during the day did not get uploaded on multiple occasions. Besides that, there is no means of adding those pictures after you uploaded the tracklog. Hopefully that will be added some day too.
