Can't submit Unlisted Request Form

Has anyone encountered this issue when submitting an Unlisted request form? I'll fill in the whole form, click submit, and get this error screen. No other information is provided about the error. This happens every time, regardless of the app which app I submit. I have submitted many of these requests successfully in the past. Nothing has changed in the information I am submitting compared to the successful ones. I am in contact with support but it's been a month of no progress so I am turning to the forums.
