More info: Users attempting to play impacted Stream videos will encounter the error message: “This browser or app can’t play the video. Something might be outdated or not supported. Try again using a different browser or app.”

Current status: We’ve encountered some delays deploying our fix addressing the previously mentioned thumbnail display issue; however, we tentatively expect that we’ll be able to begin deployment by Friday, March 1, 2024. We’ll aim to confirm our deployment timeline and provide an estimated time to full resolution in our next scheduled update.

Scope of impact: Any user may be unable to play migrated Stream videos in Microsoft Stream.

Start time: Saturday, February 10, 2024, at 2:00 AM UTC

Preliminary root cause: A recent feature update, intended to enhance the reliability and stability of our service, contained a code regression that prevented migrated Stream videos from playing as expected during the outlined window of impact.
