Studio cannot see your networks, so it asks you to confirm each post.
Mark it as posted
After you tap Post on a network and share the post, Studio asks Posted on that network. You can also tap I posted it on the post in the Publish window at any time.
Optional: paste the Link to the post. Copy it from the network's Share, then Copy link.
Tap Yes, it's posted.
The post shows as Posted. When every post for a piece has gone out, the piece moves to Published.
Cancel a post
Open Publish in the editor (on a phone, the paper-plane icon) and tap Cancel on the post, then Cancel post. You can schedule the piece again later.
Results later
A few days after a post goes out, Studio sends a notification asking How did it do on that network, unless you have already added results. Tap it to add the numbers.
