Hello Aleber,
Marketing Channel Manager and Marketing Channel Processing Rules are applicable and valid for all the Report Suites irrespective of your platforms(Website or Mobile Application or any OTTs).
But do you think you can build conditions the same way as the Website if it is a Mobile Application? Guess cannot.
For the Website, we usually use Query String Parameter but not sure we can do that for Mobile Application. So, for Mobile Application, the conditions/logic will change but still Marketing Channel Manager and Marketing Channel Processing Rule can process it without any issues if you have processable conditions.
Thank You, Arun.
