After additional experiments with sharing the Obsidian Publish permalinks on social media, I discovered that if I do so two hours after the page goes live, the image will appear on the social media post. I haven’t had any luck with a one-hour wait, though.

Next, I’ll try one and a half hours 😉

UPDATE: So, it looks like my two-hour theory is a bit hit or miss. I’m adding this update because it took a bit more than two hours for the image on this one to appear.
