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.
