Playback speed stopped working for downloaded music

Server Version#:1.42.2.10.156
Player Version#:4.12.4
<If providing server logs please do NOT turn on verbose logging, only debug logging should be enabled>

Everything works on v4.11 - switch to v4.12 and above, I run into issues.

If I stream I can adjust playback speed slow or fast and it works as expected.

Download some albums and it works fine.

Download a playlist and if I try adjusting playback speed, nothing happens?

I did a complete reset on my Samsung A34 - installed latest Plexamp, imported playlist but still cannot get playback speed to work?

if I download album as opus 256kbps - playback speed doesnt work.

download playlist as alac/flac - playback speed works

download playist as opus - playback speed doesnt work.
