Prince William may be an elder millennial, but that doesn't mean he's completely on board with all of his generation's preferences.
Back in 2018, William joked to a royal fan: "I'm allergic to selfies," but since then he has indulged many well-wishers in posing with them. Knowing him, he was probably more self-conscious about his appearance than "allergic" to the concept of selfies more generally, anyway. Still, it very much looks like the Prince of Wales has got over this particular hang-up.
