Mastodon/Fediverse:
How long does it “typically” take for a server to refresh something like a link preview? I changed the featured image on my website, but it’s been days and it still comes up as my old one on here. Is any aspect of that due to my local cache, or is it all server side? Speak to me the way you would a fourth grader.
The preview should be a dark graphic with my name, not a portrait of me.
