Course name- Content Marketing

Lesson tittle- “Why are topic clusters important”?

Hi I’m taking the content Marketing course and lesson above is not loading properly. The video keeps spinning and the lesson won"t mark complete and all lesson after it won’t load.

I done all things like refreshing page and using different browser and network but it didnot work.

here my browers link: [whatsmybrowser.org](http://whatsmybrowser.org)

Could someone please help me to reset this lesson and tell me is there any practical exercise left that intrupt the lesson loading for this course.

Hello @RLubana,

Thanks for flagging this and for the detailed troubleshooting steps you’ve already tried. I’ve found a few other threads on this as well. I’m pairing directly with the Academy team on this already to look into what’s going on with the video completion tracking, and I’ll reply back to this thread with any updates.

Appreciate your patience!

Best,

Sam, Community Manager

Hey @RLubana,

Great news - the issue should now been resolved!

You should be able to continue progressing through the course. If the issue persists, I’d suggest trying the following:

1. Clear your browser cache or open the lesson in an incognito/private window
2. Reload the lesson and play the video through to completion
3. The lesson should now mark as complete, and subsequent lessons should load properly

Thanks so much for your patience while we got this sorted!
