Dartmouth Music Supplement?

Hello. I’m going to be submitting a music supp to Dartmouth, and they use the same system (uploading via portal) as UPenn and UChicago. The thing is, for Penn & Chicago, there is a receipt after submission, indicating that they have received my videos. But for dartmouth, even when i click “continue” at the bottom of “your portoflio” tab, there is no indication or acknowledgement that those videos have been received. (just transports me back to the main page…) Anyone else submitting a music sup to dartmouth know anything about this?
