CKAD course: No way to control the course: pause, backward, forward

I have just begun the CKAD course, but when a lesson has begun, there is no control to pause, going forward or going backward.

Can someone help me please

Hi @pierrek ,
As a reference, can you please share the screenshot?

Regards,

I am sorry,
it was just the pre-lessons of the course.
After that, the lessons were stoppable, backwardable and forwardable

Thank you
