I was not getting the correct answer of Chapter 4 Quiz 2. So, after reading few forum discussions, I got to know that my data set has been changed, because of which I am not getting the correct count.
So, I just deleted all the collections, project, organization to re setup the sample database.
I restarted by creating organization -> project -> cluster. Till project, it works fine but when I navigate to clusters and try to create a free cluster, the atlas page loads and I get blank screen.
Please help me to resolve this, so that I can continue my learning.
