Playbook: debug a dropping consent string in the bidstream

Playbook: debug a dropping consent string in the bidstream
Confirmed: missing TCF strings quietly zero out European demand while fill looks fine on house ads.

— Confirm the CMP fires before the bidder requests, not after
— Check the gdpr and gdpr_consent params actually attach to the request
— Validate the string decodes with the right vendor list version
— Confirm your SSP IDs are in the CMP's vendor allowlist
— Watch EU CPMs recover within 48h once the string flows

Impact: a dropped consent string looks like soft demand, not a tracking bug. sourced
