More version details

Adaptive Bitrate (ABR) live streaming using LLHLS streams is experiencing performance issues on specified devices. Users report frequent stuttering or freezing when the stream is switching between different bitrates, while playing close to the live-edge when playback is utilizing “parts”. (This does not happen when playing further behind the live-edge, e.g. 30s or more, or using normal HLS )

Additionally, a black, shady glitch occasionally appears during the bitrate transition. These issues significantly impact the viewing experience.
