In the support chat (the bubble in the corner of the screen), the header has:

  • Previous conversations (history icon): lists the conversations you've had with support. Click one to reread it in read-only mode.
  • End conversation: closes the current chat. When you come back, you can choose Continue in this conversation or Open new conversation.
  • New message sound (speaker icon): turns the sound alert on or off. It plays when a reply arrives and you're not looking at the chat. On by default.

When support replies while the chat is closed, the bubble shows a red badge with the number of unread messages, and you get the notification Support sent you a message. The open conversation also appears in any other browser or device where you're logged in.

Is the bubble covering a button? Click the × in its corner: it disappears until you close the tab and comes back when you open Ads Editor in a new tab.
