Stage blackens when I select transcript

Hello John!

Thanks so much for reaching out. Sorry to hear your reviewer is experiencing this issue. 

I'd recommend a few things for your reviewer:

• Please have them try clearing their browser’s cache and cookies
• If that doesn't work, I would also recommend attempting to view the course in a different browser and see if that changes their experience. 

If they are still having trouble, please let us know and we would be happy to put you in touch with our Support Engineers in a support case. 

Have a great day!
