Hey, thanks for the report. This is a known regression in the 2.6 series and it’s already being discussed here: Regression Chat history UI in 2.6: can't delete, rename, see current selected agent chat
The team is aware of the issue. For now, as a workaround, switch to Agent Mode. In the sidebar there you can do all chat actions like delete, rename, and access archived chats. It’s not ideal, but it works.
Let me know if there’s anything else.
