Escalate late approvals, open follow-ups, remind reviewers. Every one is ready to run, and you can adjust it in plain language.
Your reviewers see the current asset file in their task, or a clear request to fix a stale link before review.
Your campaign owner sees deadline changes beside assets in review, so they can confirm the reviewer still has time.
Your launch team sees reviews due soon, what is blocked, and who needs to act next, together in chat before the launch window.
