If state changes in parent component, all the children components are also re-rendered. So I would suggest going up the component tree and check if state gets updated there

> If state changes in parent component, all the children components are also re-rendered That's incorrect.

Maybe you encounter the "square vs bracket" case? > The round version causes the greet hiccup for all children to be incorporated into the hiccup returned by the parent, forming one large data structure, parent and children all in together. So, each time the parent re-renders, all the greet children are effectively re-rendered too. React must then work out what, in this tree, has changed.

You can try using React DevTools.
