Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: !brighton@feddit.uk

LW is federated to feddit.uk.

It can take up sometimes minutes, sometimes an hour to sync comments and posts. Depending on the availability of LW and feddit.uk.

In your case, I see it has not synced at all.

I have read the outage logs and LW was fully operational at time of posting.

So as far as I can see, the issue is most likely a problem on feddit.uk or a syncing error bug on Lemmy itself.
