Summary
I realized that when i double checked my presentation and realized that the codepen examples in my slide were not working. Then i went to your website and realized that this is issue does not only exist on the activity component but in other components live example sections too.
Please ignore if this is some kind of connection issue but i have been looking at the documentations for a long time and this is the first time i have encountered such issue.
Best Regards.
