Hey, this is a known bug linked to a specific chat panel layout state. There’s a workaround: click the double-arrow icon at the top right of the chat panel. This toggles “Swap Agent Sidebar Location”. It should slightly change the layout and make chat history clickable again.
More details in this thread: [2.6.11] Clicking On Chat in Chat History Not Working
Note: pressing Cmd+E toggles the same setting and can bring the bug back, so please avoid that shortcut for now.
The team is aware of this issue. Let me know if the workaround doesn’t help.
