Once you have created your event and made your way through the settings to the event landing page template (which you can access and edit at any time once the event has been created) you will be able to add a section with your Instagram feed.
To do this, locate the 'Instagram feed' block in the 'Social' section of the deign components, then click and drag the blog into the desired location on your event landing page.
Once the block is in place, click on it to open the component settings on the left hand side of the screen. Choose the 'Instagram feed' option from the settings, and then click on the 'Click here' hyperlink. This will open a pop up.
On the pop up you will need to log in to your Facebook account that is linked with the Instagram Business account you want to display.
Once you have logged in, the latest posts from your Instagram account will display, and update themselves as you post more on Instagram.
