BUG in GA4 Organic Search Channel

The definition of the Organic Search channel in GA4 states that:

☑ Source matches a list of search sites listed under “SOURCE_CATEGORY_SEARCH”

👉 AND

☑ Medium exactly matches organic

So 2 conditions are required for the session to be attributed to that channel.

In the comments of a previous post of mine, a user attached a screenshot in which a session with source “google” and medium “(not set)” was associated with the channel Organic Search… 🤔

Amazed by this inconsistency, I carried out some tests and discovered that not only “google / (not set)” is associated with the Organic Search channel, but also:

😱 bing / (not set) –> Organic Search
😱 (not set) / organic –> Organic Search
😱 appsscript.it / organic –> Organic Search
😱 google / referral –> Organic Search
😱 google / test123 –> Organic Search

Check out the screenshot below!
