What and when you can edit

Arrow has a 5 minute pre-launch content lock. If you wish to make changes within this 5 minute window, you will need to move the CTA scheduled publication time further into the future.

When the campaign is live:

• The instant notification Tweet and scheduled notification Tweet(s) copy or assets can be changed at any point while the campaign is live.
• The end date and time of the instant notification Tweet can be changed at any time before the end time has been reached (*applicable to Instant Notification campaigns only).  
• The date and time of the scheduled notification Tweet(s) can be changed at any time before the scheduled notification processing starts.
• The authorized account and the CTA Tweet cannot be changed once the campaign is launched. However, additional CTA Tweets can be published. See Adding CTA Tweets section for more.
