With Boost, you'll have full editorial control of your ads. You can edit your ads in your Boost dashboard anytime.
In the dashboard, tap on "View" next to any of your live ads to make edits.
Next, tap on "Edit Campaign" to make changes to the way your ad looks.
You can make edits to the headline, photo, title and description. Any changes you make will be live on your ad within the next 15 minutes or so.
Remember: You can make edits to your ad anytime while it's running! So if you miss the email letting you know your ad is about to go live and want to edit it after it's already running, thats ok!
