What does "Ready, waiting on Meta" mean?

It means your plan is approved and marked ready, but SizzleGo's connection to Meta is still waiting on Meta's approval. Nothing is spending. The Ads page shows a note while Meta is not connected yet, and says we will email you when campaigns can start.

While we wait, the button on an approved campaign says Mark ready. Once the connection is live, it says Connect Meta. Meta asks you to sign in and grant ad access, then the campaign shows Running. Your card stays on your Meta account.

If you see That Meta sign-in link expired or Meta did not grant access, click Connect Meta again. Only someone who can publish Ads, like an owner, an admin, or a Manager on Ads, can connect Meta.
