Config command or Google tag required for custom events
'This update prevents custom events from being sent independently of the tag configuration, which previously caused (not set) attribution values.'
Source: What's new archive — Nov 13, 2024.
What it breaks
Custom events fired before the Google tag loads stop being processed; a pipeline that sent events without a config silently loses them.
Who it hits: Sites with custom gtag events fired early or from separate scripts.
The fix
Confirm the Google tag loads before any custom event (the audit's first check).

Source group and UTM audit checklist
The checks that keep channel reports honest through Google's dimension changes: the Google tag before custom events, one family of traffic-source dimensions per report, Source Group vs raw source, the primary channel group frozen and documented.
