Default channel grouping not in line with GA4 default channel grouping

[erikverheij]

Hello,

Firstly, I'd like to express my gratitude for this incredible package; it has been immensely beneficial in my work.

While reviewing default_channel_grouping.sql, I noticed that the "Paid Other" channel group, which is a default in GA4, appears to be missing. The documentation from Google Analytics for the "Paid Other" channel group is provided here: GA4 Default Channel Groups.

For reference, the "Paid Other" criteria is defined as: Medium matches regex ^(.*cp.*\|ppc\|retargeting\|paid.*)$

Upon further inspection, and while comparing with the GA4 documentation, I observed a few discrepancies:

• Other Advertising: It appears this might not be a part of GA4's default channels anymore.
• Push Notifications: The GA4 documentation now refers to this as Mobile Push Notifications.
• Cross-network: This is defined in GA4's default channels, but I couldn't locate its presence in macros/default_channel_grouping.sql.

For visual reference, please see the image provided:

I hope these observations prove useful, and I'm eager to contribute or assist further if needed. Thank you for your continuous effort in maintaining and improving this repository.

Kind regards, Erik

Very useful! Thanks so much. Do you feel comfortable submitting a PR to resolve these discrepancies?

It does make me wonder if Google changes these from time to time as I thought our implementation was correct as of ~6 months ago 🤔

Thanks for your reply :) I'll create a PR in the upcoming weeks!
