Picture-in-Picture does not work properly. Subtitles are displayed twice on Netflix.

I discovered that the controls in Picture-in-Picture also don't work whether subtitles are displayed or not. Specifically, the pause and play controls do not work. The others work.

It is a known issue and it will be fixed in a future update release.
