Hello!

I’m currently teaching Lesson 10. I discovered that both compression widgets (one with no image selection and one with image selection) will not generate a result after moving the slider. It will show a loading symbol indefinitely. I am working from a Chrome browser. Would this be a localized problem or is anyone else having the same issue?

Thank you!

It is not working for me either. Please report this to [support@code.org](mailto:support@code.org).

I also had this issue when teaching this lesson today.
