I share a lot of files through my Google drive. Recently I noticed a problem where I couldn't play them in that Google drive, though it looks like people who downloaded them were able to play them outside of the drive.
I did some research and it looks like others started having the same problem which seemed to start happening on the 19th of this month.
I have a feeling it's just some type of temporary glitch and hope it doesn't come from some change Google has made.
