iOS 15 - HLS parallel download issue

Hi,

We are using AVPlayer for FPL HLS stream, after migrating to iOS 15 (currently Beta 3), we have observed a strange behavior during segments download;

1. The player downloads last video segment of VOD HLS stream
2. The player downloads all audio segments
3. Playback starts playing from the end (last segment)

Needs to restart playback to start downloading all video segments.

Note that we do not have this behavior with older versions of iOS (14 and before).

Thank you,
