Are you redirecting to njump? Because njump has a bug that doesn't update the profiles. So when people visit an nprofile or npub on njump, they're presented with incorrect information. The user's relays, NIP-05, and LN address are all typically inaccurate. Alternatively, you can use nosta.me, which provides all the same info as njump, but it's accurate and instantly updated. It also looks a lot better, IMO.
