As i already said, i dont think this is chapter specific issue, but still, here is the chapters link: Chapter: https://www.khanacademy.org/science/physics/quantum-physics/quantum-numbers-and-orbitals/v/heisenberg-uncertainty-principle

So this is on the Khan Academy Android App, correct?

Also, you can take a screenshot of the screen record and upload it there, which will help us better understand your issue.

Hey SP

Yes.As I have mentioned already, this is spotted on Khan Academy Android App (the app and OS version mentioned in the original description - I am editing it now for more clarity and pasting the links from the video description to here, okay?)

And I am uploading the screenshot from the recorded video. It is not of good quality though (the buttons are broken, so... @_@ ).
