Thank you for your post, and I am sorry for the inconvenience!
This sounds like it may be an issue with your cache or cookies not recording that you have been through the tutorial. Would you mind trying the below and let me know if it helps? Instead of clicking the 'x' on the pop-up, clicking on the background should close it.

I have this same problem! I have tried everything! I've gone through all the tutorials several times, I've erased all my cookies and history, I've accepted the cookies on the site, I've added the site manually to accept cookies through Google Chrome and nothing has worked!
