How to notify Unity3d team about and issue in Tutorial?

Hy guys.

I'm a quite experience developer and passing Unity Tutorials script part is most clear part for me. But I suppose for some users who are new in coding this might me huge problem.

At the "Tic-Tac-toe tutorial #6 Wind conditions and taking turns" there is a line in tutorial, without generic function that leads to error in compiler. And I think this bring a lot of despair during tutorial passing for some newbies.





buttonList.GetComponentInParent().interactable = false;




but this is call without generic instruction about type, so this code fails. Need to write like this.

buttonList.GetComponentInParent<Button>().interactable = false;


How to notify Unity3d team to change this line in the tutorial?
thank you
