Submit a video of yourself on the ball. Let your game do the talking.
Check that you have a strong enough network connection, make sure you are in an area with very strong signal. Alternatively connect to a WiFi connection. Uploading a video can use quite a bit of bandwidth depending on the size, so you might just need a faster network connection.
Once a video is uploaded, you should see a notification at the bottom of the form, if you are certain you did not miss it and you are concerned that the video did not upload. You can send us an email and we will confirm that we received it.
