The tool introductions have gone, or I want to switch them off

How much coaching is shown is a personal choice, and changing it never affects data or results.

• Guided shows the tool introductions, step-by-step guide strips and fuller hints. Expert hides them for a quieter screen. Switch between them with the Guided | Expert toggle in the top bar.
• Choosing Don't show these again on an introduction switches to Expert.
• To bring every introduction back: open My Account from the sidebar, go to Settings & maintenance, and under Guidance level choose Show the tool introductions again. Walk me through it or I know my way around are also available there.

This choice follows between devices.
