Can't upload ID

I would like the link to upload my ID. I opened the notification and log out of it. I took pictures of my I'D and the notification was gone. I'm afraid to mail this person their order if I don't get confirmation that I am setup to receive payments.

SAME ISSUE HERE!!! I TRY TO UPLOAD THE IMAGE OF MY ID, IT LETS ME BROWSE FOR THE FILE AND CLICK UPLOAD BUT THEN IT NEVER UPLOADS ANYTHINGS, IT JUST RETURNS ME TO THE SCREEN WHERE IT SAYS CLICK TO UPLOAD, AS IF I NEVER SELECTED ANYTHING TO LOAD. I EVEN TRIED MAKING MY PHOTO A COUPLE DIFFERENT SIZES SMALLER AND LARGER AND I ALSO TRIED USING UPLOADING USING A DIFFERENT PHONE, STILL NOTHING!!! SO I JUST CLICKED SUBMIT, MAYBE MY PHOTO IS UPLOADED ON THEIR END AND INVISIBLE ON MY END..
