New preview update for Alpha Skip Ahead / Alpha Insiders, and it includes a new feature...

Are you on the Xbox Insider previews? If so, they are changing it for something else. Can't recall offhand but it's in the release notes from a couple weeks back.

Is your console enrolled in the Xbox Insider Preview Program?

In May they have issued a fix for video corruption on Netflix and YouTube for Alpha Skip Ahead
