How to Turn off Wifi Setting in Mi Phone for Downloading EdX Videos

I came across a problem today that after installing Edx app on my MI Phone, videos are not getting downloaded. It always say that "Your current settings only allow downloads over Wifi, Please connect to a wifi or change the download settings". 

To change this download setting you need to follow the following steps:

1. Open the Edx App
2. Click on Nut like button on the top right corner.
3. Click on Setting Link.
4. Turn off the wifi only download.
5. Again go to video and click on download.
6. Now the video starts downloading.
