NPAW session resolution by platform (5 rows)

Editable before send

Description

NPAW session resolution to an AUMS UUID dropped to 94.2%, below the 95% floor. The shortfall is entirely Tizen and tvOS, whose payloads are absent from the interim S3 delivery. Every QoE metric for those two platforms is therefore labelled partial rather than reported as complete. This is a detection-capability alert, not a service alert.

Suggested action

Escalate NPAW Data API access (§16 Q4). Until then, keep Tizen and tvOS QoE flagged partial on every surface.
