at the home page, the message prompts you to jump to the Detail component to initialize the data that can only be rendered from Control. Clicking on a new message here will not trigger constructor, so I am dealing with nextProps data. If the time of the first question is not over, the two countdown times of the second question will be running, and the time will be reduced at double speed.
I have cleared the timer wherever I can think of, but there is still a problem. Ask for help
