After you've clicked View All or on the People Hub tile on your dashboard, you'll be brought to the feed. Then, you can click the Create Post button to start your announcement.
First, you'll enter your message. Note that most emojis are supported if you're on a mobile device. If you add a link in it will be clickable, but not able to be hyperlinked in the message. You can't add any files or attachments.
Then you'll choose who can see the post from these options:
- everyone in the company
- your team (your manager, peers, and any of your direct reports)
- specific locations and/or departments
Once you click Post, the audience of the post will be notified of the announcement via mobile push notification if they have that turned on.
