The documentation for mobile tracking can be a bit spread out. You linked to a tutorial, but https://developer.adobe.com/client-sdks/home/getting-started/get-the-sdk/ has some other details (and if you're on React Native, there's a whole different set of docs to keep in mind). 

I've had similar issues, where "", null, and nullify() all throw errors (eg, The source field iif(xdm.web.webPageDetails.name.equals("Subscribe"),1,"") is null or not found) when the condition isn't matched. BUT... for me it has only ever affected that field. The errors don't seem to affect anything...

Attached is the second Toolkit. This one has a lot of material in the first half on Adobe Workfront- this won't be featured much in the exam, but it'd still probably be a good idea to get loosely familiar with it. However, there is a section on Adobe Analytics Documentation that you absolutely shoul...

Hello, Everyone! Attached is the Toolkit for the first Module, "Understanding Analytics in the Adobe Experience Cloud Ecosystem". It includes 3 sections:1. A general "what is Adobe Analytics" with a lot of good links for learning the technical side of Adobe Analytics2. Setting Analytics and Experien...

These are the questions that remain AFTER I've spoken to account reps:) (which, in general, as a consultant, I don't have much access to, though a few have kindly met with me and answered some of my questions and helped me understand the different options for purchasing, just not the nitty gritty of...
