Push notification is one swift way to connect to all your learners, all at once. All you have to do is compose the important piece of message and hit on send, and all your learners, irrespective of which device they are on, will receive your notification.
So let me tell you, how you can send a push notification from your admin account.
First login to your admin account and click on Marketing > Messenger > Push
Click on "Create New Message" in the next page
In the next screen, compose the message and add all the details then click on SEND.
And when you send the push notification, it will appear on your learners tab, who has "allowed" the push notification.
