How do I find and reply to a message in a case timeline on mobile?

1. Scroll down to the timeline on the case details page, or tap the "Timeline" tab at the top. 2. Find the message you want to reply to and tap it to return to the original discussion thread and reply. 3. You can ask: "How many messages are in this case's timeline?" The AI would respond: "There are 20 messages in this case's timeline."
