That's interesting. I would expect your "Email" channel to get reported, even if you're building a freeform table with Marketing Channel dimension and Visits metric. When you debug your AA hits, for the "g" parameter in the beacon, do you see your full URL with the "utm_medium" parameter too?

Normally, I'd use Cohort Analysis (https://experienceleague.adobe.com/docs/analytics/analyze/analysis-workspace/visualizations/cohort-table/cohort-analysis.html?lang=en) for a report where I need to answer "what percentage of X visits (or visitors) in a previous period returned (or churned) in the n...

(Not answering your question directly) Take note that with growing awareness of data privacy and browser blocking technologies, visitor identification could be becoming inaccurate. For example, a user who tends to open your same website in private windows will always get identified as a new visitor ...

The out-of-the-box schema provides a 1-to-1 mapping between the schema fields and Analytics fields: https://experienceleague.adobe.com/docs/analytics/implementation/aep-edge/variable-mapping.html?lang=en If you use your own custom schema yet you want data to appear in Analytics' props/eVars/events/e...

Yeah, those are the most likely sources of the abbreviations. Honestly, I don't really think about their origins any more. 

@Adnan-Sait I second this approach.

I assume that you're seeing these in URL query parameters. Adobe Analytics doesn't dictate the query parameter to use for campaign tracking, both external (e.g. from paid search, social media, email, etc) nor internal (e.g. homepage banners, product promotions, etc). So organisations come up with th...

Classification works with data that have already been tracked. So that won't work for you since your order IDs are not tracked at all. You can consider the Bulk Data Insertion API https://developer.adobe.com/analytics-apis/docs/2.0/guides/endpoints/bulk-data-insertion/ . However, that requires that ...

@Jennifer_Dungan yeah, that's probably what I saw: re-installations.

@Jennifer_Dungan thanks for clarifying that new app versions don't result in new ECIDs for the same devices. I thought I had read somewhere that that happens, but I guess I had read wrongly.
