How do I report something a companion said?

Tap the ⋯ button under the newest reply, or hold any older one, and choose Report this reply. Pick what was wrong with it, and add a few words if you want to. We receive that reply, the message you sent just before it so the reply makes sense, and which AI model wrote it. In a group chat you are asked which member said it. You can report a reply from a companion you made yourself.
