Attribution Issues in Marketing Channels
Hello Adobe Community!
I've been trying to solve this issue for months since we switched from the old report suite to the new one.
As you can see in the old report suit, this is the traffic we used to receive, with more specific channels like paid search, email or QR Codes.

On the other hand, here is the new graph with the new report suite.

So, here is the order in which the marketing channels are configured:

It's important to clarify that the same configuration we have in the old report suite is what we have in the new one we switched to.
finally, here are examples about how we used to configure some channels like paid search.

So my question is about whether you know of any generic filter that could potentially help me configure the channels (at least paid search, email, QR).
Is it possible that the campaigns we are trying to attribute do not match the filters and are attributed to more general channels like direct, internal, natural search, or referring domains?
What could be a good approach to solve this problem?
Do you think that monitoring campaigns being generated and filtering by their query parameters could be the key to assigning the channels?
