Social networks ask for permission again from time to time, or when you change your password. When that happens the channel shows that it needs attention and posts to it can't be published.

• Reconnect: open Channels, find the account and choose Reconnect. Sign in again and confirm.
• Pause: stops publishing to that account without removing it. Choose Resume to start again.
• Delete: removes the account from Wiply Studio. Its scheduled posts won't be published. Nothing is deleted on the social network.

Use the search and filters in Channels to find an account, or select several to manage them together.
