Hey, my love! It depends - we never really understand the entire context of a situation (whether the author has been privately contacted, if the person who received the gift is online or has the time to properly read the gift or any other personal circumstances that can influence this situation). If it's happened to you, maybe, contact the author? AO3 doesn't notify you when you are gifted a fanfiction and often times, authors don't check the gifts section of their profile! 🥹

• Thanks to your ask you actually reminded me that I still had yet to kudos & bookmark a fic that a very wonderful and kind person gifted me a while back (that, unfortunately, I haven't had the time to properly read it because of personal matters);

Thank you for asking!!! 🌼🌻
