I just realized that this place is only meant to be for documentation suggestions - sorry. I would like to suggest that a couple of photos would help, e.g. one showing the upload bar (as I said, on my device it is at the bottom of the screen) and what it means that “When the status message in the top left of the device’s display reports that the process is complete”. I didn’t get such a message, it is just that the upload bar is full. However, maybe that is the problem?
