Prior to "Bridgerton," Ashley was also known for her role as Olivia Hanan in Netflix's comedy-drama "Sex Education." The acclaimed series dives into the lives of those at Moordale Secondary School, including teachers and students, as they deal with the sometimes difficult world of sexuality and sexual experiences. Olivia is part of "The Untouchables" clique of popular, rich students at Moordale and is impersonal, but she becomes a client in classmate Otis Milburn's sex therapy to help her navigate her self-esteem issues around sex.
Ashley had a recurring role as Olivia in the series but will not be returning for the show's fourth season. She told Glamour in March 2022, "I think my time on [the show] has come to an end. It's very sad because I love them all so much."
