What does the gear icon at the top right of mobile Dashboard do? How is it different from the icons on the top left?

1. There are two icons on the top left: the leftmost "≡ hamburger menu" expands the side navigation menu to switch between function modules; the "💬 message icon" to its right opens the message or notification center. 2. The "⚙ settings icon" at the top right is specifically for opening Analytics-related settings, such as adjusting the display content or parameters of Analytics. 3. If you need customer service assistance, click the "🎧 support icon" (pink floating button) at the bottom right of the screen to contact the support team.
