Insufficient power: Murphy's juice cup is not used for a long time, or the power is charged to the lowest level. If double-clicking the button doesn't respond, you can charge 1-2 hours, and then try to double-click to start.
Improper operation: when double-clicking starts, the time interval is too long, or the double-clicking speed is too fast. You can adjust the operation time and try double-clicking to restart.
