Chat in the mobile app now gives the screen to the conversation. Each message shows its author and time once, followed by the text; further messages from the same person within a few minutes follow without repeating the name. Reactions and reply counts appear only when a message has them.
Tap or long-press a message, or choose … beside the author, to react, reply in a thread or delete it. The composer is a single row at the bottom: + attaches a photo, a voice note or files, and attachments waiting to be sent appear above the message field, where each can be removed. The limits for each kind of attachment are shown when you choose it.
