Google Analytics client no longer serves Google script dependencies on server-side Tag Manager
'Now serve ALL your scripts (for example, gtag.js and gtm.js) with the web container client. The Google Analytics client no longer supports dependency serving for Google scripts.'
What it breaks
New tagging servers that rely on the GA client to serve gtag.js or gtm.js serve nothing; pages load no tags.
Who it hits: New server-side Tag Manager setups after 30 Jun 2025 (existing clients unaffected).
The fix
Serve every Google script through the web container client (menu path in the checklist).

Every step named by menu path, never by picture — it survives the interface redesigns that make every screenshot guide wrong.
