In the test code the movies count is set as 23530, but in the “movies” collection is 23539 
I spent some time to get this inconsistency in the material. Other test numbers might be off, too… 
Hi @cciotescu,
We made changed to the dataset 1 month ago, please delete the dataset from your cluster and reload it again through Atlas.

Thank you Kanika,
I did the way you advised and got
I will wait a bit longer, perhaps it needs to replicate some data.
I will delete all data sets due to the cluster is limited to 500 MB, and the sample databases take like 403MB…
Awesome! Good luck.
