Not sure if the last app on IOS version is broken

[LoLoEmby 1]

Hello great people!
Recently I facing a black screens and no sound (only subs) on my iPhone and Mac with the last apps version while playing some content like movies / tv shows that require or forced to transcode.

After a lot of digging i found that enabling the "Disable HLS Subtitles" option in the "Diagnostic Options" Manu is the resoen of the black screen.
If I leave the settings "Disable HLS Subtitles" untouched there is image but any subtitle is becoming gibberish and it choose the first subtitle in the list.

I'm using the "Disable HLS Subtitles"  because it fixed the out of sync when you fast forwards see the post  here:
https://emby.media/community/topic/147466-subtitles-going-out-of-sync-when-transcoding-sound/

I tied rebooting the Emby, the server physically, changing transcoding settings back and forward and reboot after each time, uninstall the Diagnostic Options addon, several devices but I was not manage to fix it.
till 5 days ago it was good from the last app version for IOS 2.2.54.

The test I made:

- Direct play - no Issue at all (Picture, Sound, Subs)

- Transcoding and "Disable HLS Subtitles" enable - issue with (Picture, Sound)

- Transcoding and "Disable HLS Subtitles" disable - issue with (Subs)

- Transcoding + "Disable HLS Subtitles" enable with no subs at all - no issue (Picture, Sound)

*On Emby for Android app and Chrome browser all tests was playing without any issues.


logs with 01 =  Transcoding and "Disable HLS Subtitles" enable - issue with (Picture, Sound)

logs with 02 =  Transcoding and "Disable HLS Subtitles" disable - issue with (Subs)
