Consistent Playback State Across Screens
Realigned playback flow so the mini player, reels, and video transitions all reference a single shared playback state.
Two issues were affecting playback reliability: video transitions in reels lagged behind the audio state, and the mini player occasionally displayed track information that did not match what was actively playing. These inconsistencies do not appear in feature checklists but directly degrade the trustworthiness of the playback experience.
The work focused on realigning the playback flow so that all related surfaces — video transitions, looping behavior, mini player display, and reel scroll position — reference a single shared playback state. Per-screen logic that independently derived playback status was reduced, ensuring visual output and audio state are driven from the same source.
Content exposure in search and recommendation was aligned to the same standard. Because playback is the most frequently encountered flow in the product, consistent state across all entry points is a foundational quality requirement.
