Been catching up on some old series during the lockdown, and just letting y'all know it seems Part 14 of MGS:4 is broken. I've tried to stream the video in different formats and quality levels on the desktop site, mobile site, mobile buddy app and luchadeer apps for android and the video player app on the Microsoft Store. They all either time out to a black screen or come up with an error message.
On the site, it basically fast-forwards to the end of the video and the replay button in the corner appears, and on my history, the video is down as watched.
As another side note, downloading works fine so managed to watch it that way.
