I can not go further Day 1, it says "Day 2 is not editable at the moment. More days will be available after you have finished Day 2". It was yesterday and decided to wait but today is the same.
Also the page suddenly appears in spanish and when I picked "english", it appears in english mixed with spanish and the video is not the same is the spanish version.

I tried on chrome and mozilla and has the same problem. 

I appreciate your help. Thanks in advance.
