Delay in WP Discourse comments appearing

I’m unaware of there even being such a thing, do I use a plug-in for that?

I’m new to WP with only one other site I help manage, this one has only ever been used as a blog and does not contain much at all on the back end, can you advise any good solutions to the cache issues?

One thing I’ve noted, not sure if it relates, this is not always present

as in I don’t always see it on my screen at work, both of those screencaps are this morning
I assume its related to WP but don’t actually know

Thanks so much
