Facial expressions and autism

Hi. Sorry for spamming these forums, but as a 40-year-old who is finally pursuing a diagnosis, I have so many questions.

This one is about recognising facial expressions. I have read that many (most?) autistic people have issues with understanding facial expressions. However, I don't think I have this deficit. Maybe I have learned to understand the cues over the years, or maybe I never had this issue to begin with. What are others' experiences? Have you been diagnosed but don't have this problem? Thanks
