Description

DRM-9010 Widevine licence denials are running at 0.84% of play attempts against a 0.21% baseline for this cohort. Volume is small and stable rather than growing, so this is quality debt rather than an incident. It sits in the sub-P1 register for the monthly service review.

Suggested action

Bundle into the monthly service review unless affected users exceed 5,000 or the trend turns upward.
