hi guys！

I got the PowerPoint yesterday, and then upgraded the firmware of the control panel. After the upgrade, the LED remained green for more than an hour. So I turn off the mouse and try to connect to the computer. After connecting Bluetooth, the mouse is always in tilt mode. Turning off the tilt mode in the control panel can be used as a normal mouse, but I can't enter the tilt mode through tilting. How to fix it?
