This is a known issue, and our engineers are looking into it. We'll have one of our agents reach out to you directly via support ticket regarding this concern. Thank you for your patience.
Same issue, very frustrating... dates back several days, so presumably hundreds if not thousands of us cannot submit proposals ?
Perhaps there should be a button on the error page asking "If you believe this is an error" please click here. Then the code could Compare the Location details, print out a BILLBOARD and live feed it to the WORLD... someone in the right place will see it eventually.
I also received a vague message after submitting a propsal (perhaps the same problem) , "my organization does not qualify" or similar, i cannot recreate this.
