In case the upload is taking really long, something might be wrong, e.g. you closed the field software before the upload was finished or you're having issues with your internet connection.
Try once more to upload the data, following these steps:
You can select one or multiple missions for upload and initiate the data upload using the “Start” button. It can take some seconds before the actual upload is starting, the progress can be followed on the screen.
Leave the application open and do not shut down the PC before upload is finished!!
When the data has been successfully uploaded, this will be indicated in the “Mission list” on the “Mission overview” page
