[Publish] Facebook Page mentions
You're able to mention other Facebook Pages in posts that you are scheduling to be shared to a Facebook Page. To mention a Facebook Page in your post, type in the @ symbol and start typing the first few letters of the Facebook Page you’d like to mention. Matching results will be returned and you can click on the Page you'd like to include.
Please note, it is not possible to mention Facebook Profiles, only Pages. Additionally, it is not possible to mention Facebook Pages if you're posting to a Facebook Group.
