You are still allowed to apply ED1 to some QB schools following the match. My D19 wasn’t matched and she actually received an email invitation to roll her app over to ED at Penn, but she’d already rolled it over to ED1 at Haverford. It was a simple emailed request- no extra info or work required, and she was accepted ED a week after the match round concluded. She also got her FA letter the very next day with enough time to fix a error on their part and speak to the FA office multiple times before the acceptance deadline, which they also offered to extend to decide if the package would work for us.
