presentFullscreenPlayer() doesn't work properly on iOS. (only audio is played)

Bug

I have some Issue, In iOS, when presentFullscreenPlayer() of video ref is executed, it becomes fullscreen, but the video stops after 2-3 seconds and only audio is played.

Platform

Which player are you experiencing the problem on:

• iOS

Environment info

• IOS Simulator (I haven’t tested it on a device yet. But it seems to be the same.)

Steps To Reproduce

1. using <Video/> component, and add Ref. (set controls property is false)
2. When I click custom fullscreen button, fullscreen player open, the video is stop after 2~3 seconds in IOS (but, the video’s audio is running continue)
3. I’ve tried using both the fullscreen property of <Video/> and presentFullscreenPlayer() but it’s the same issue in IOS.
4. The full screen function using the controls property works fine, but the above issue occurs when using presentFullscreenPlayer().

…

Expected behaviour

1. Using presentFullscreenPlayer() should play the video normally.

Reproducible sample code

const presentFullScreen = () => {
    // setIsPause(true)
    videoPlayer.current?.presentFullscreenPlayer()
    videoPlayer.current?.seek(0)
}

return (
<Video
        ref={videoPlayer}
        source={{
          uri: videoUri,
        }}
        paused={isPause}
        playInBackground={false}
        style={{
          width: videoWidth,
          height: videoHeight,
        }}
        controls={false}
        repeat={true}
        // fullscreen={isFullScreen} it's same issue
      />
)

Video sample

If possible, include a link to the video that has the problem that can be streamed or downloaded from.

@Tony0205 I have this only on a simulator. I’ve never had this issue on a real device.

I have exactly the same issue on iOS. Both on simulator and device.
