Its likely some relay has an old version of your profile. It will update eventually. Could also be cached data, client side.

You can republish single notes to a single specific relay with fevela.me & jumble.social .

Not sure if it's quite there yet, but keep an eye on

nostr.band and the web app of nsec.app are down. Likely permanently, as they have been gone since the end of last year. You probably should look into using a different signer.

Primal had a caching server in the middle that fetches from relays, then serves notes & notifications to you from there. You don't actually read anything from relays in Primal, though you do still write to them. It reduces bandwidth & creates consistency within their environment, but it can miss some events or take extra time to aggregate. Alternatively, you might notice things missing in Nostria, on occassion, if it has difficulty connecting to either your relays or the relays of your contacts. This latter situation can affect any client. Many, like Nostria, use a list of fallback relays to try to reduce the effects of poor connectivity. Primal's situation is unique to Primal.

You'll notice this across all clients, to some extent. Clients use different methods to fetch your mentions from many relays. There is also some variation in where/how the sender's client sends these events.
