What it shows

  • A single billing account isolates multiple personalized viewer profiles.
  • Episodes share catalog metadata through a parent series hierarchy.
  • Playback markers record millisecond offsets independently per profile.

The takeaway

Tie playback telemetry to the profile, not the account or raw video asset.
