Hi, I'm working on the Extract External Data into Analytics module and when I upload the .csv file to create the dataset, it failed twice.  Any ideas?
Thank you.

Hi there.  I'm working on the Wave Analytics Trail and I'm on the "Security Predicates" topic.  The instructions say:

On the Analytics home tab, click Browse All.
Click Datasets.
Hover over a dataset, click the action arrow , and click Edit.
Scroll to the bottom of the page, to the Security section.

When I go to my wave dev org and click on the Analytics tab, I don't see anything that says "browse all" or "datasets".  I have two categories:  Apps and Dashboards.  I'm not sure how to proceed.
