After the video has finished loading, it does not autoplay. Loading process: VimeoPlayer.autoPlay = true; VimeoPlayer.LoadVideo(vimeoID); VimeoPlayer is attached to Canvas. We've seen up to the call to OnVideoMetadataLoad(). OnVideoStart() was not called. VideoPlayer.Prepare() and VideoPlayer.Play() in OnVideoStart(). But it seems to stop somewhere in there. Once another app (browser, etc.) is displayed in front, playback starts. It does not reproduce on Editor, but occurs when built as a macOS app. If anyone knows the cause, please let me know. Best Regards.
