Adding emojis to your article works a bit different than adding an emoji or icon to your collections. In case you want to add an emoji to show up in your help article title all you have to do is:
Add the emoji directly to the article title (instead of using Notion’s dedicated icon feature)
That’s it 🥳
Ultimately, we would like to also use Notion’s icon feature for this. Due to Notion’s way of handling data we have to default to this workaround instead. We are constantly monitoring Notion’s progress to see how we can improve it.
