My sense of smell still sucks, and it's been almost two years since I had COVID. It's marginally better than it was, but is still substantially worse than it was pre-infection.
EDIT: Okay, this is a bit of an exaggeration. My sense of smell has mostly returned, but for example, nuances in the taste of food seem to have become permanently dulled, and it sucks tbh. Something, as subtle as it is, has changed.
