To ensure that you are logging onto the Virtual Lab correctly, here's a YouTube video that illustrates how to access SAS Drive when using Virtual Lab 1 for the Machine Learning class: http://youtu.be/7Y4iVp1SYuU?hd=1 . (That class was used as an example because it shows using the student/Metadata0 credentials and the SAS Drive link from Google Chrome). As you can see on this video, the SAS Drive favorite is on the bookmarks bar in Google Chrome in the Virtual Lab. At time stamp 1:53 in the video, you see the instructions that I am following and then you can see how I log onto SAS Viya using those credentials.
Hope this helps,
Cynthia
