We know that you're likely excited about uploading all those scorecards to get your handicap but please don't use the "Back" button on your web browser.
In the pop-up that is displayed confirming your previous card has been successfully uploaded, there is a small "X", use this to exit the screen and return to the Member Dashboard.
At this stage you should be all set to upload the next one, if you're still having issues, let us know.
