I’ve also noticed issues with google drive. The 720p video seems fine but the 1080p video is showing as a 0 byte file that won’t play in browser and all it will let me download is the 0 byte file.
I see all four versions there. Does the file appear but cannot be played in-browser?
They all have commentary, and I don’t know why Google Drive presents it as the only audio option in-browser. But you can download whichever version and select whichever of the audio streams you like.
