Issue summary: From December 13, 2022 at 11:46 AM PST to December 14, 2022 at 7:30 AM PST some customers may have experienced issues while playing videos.

We determined this issue was caused by a recent frontend change that caused a failure to load videos via the streaming protocol HLS (Hypertext Live Streaming), for which no fallback existed.

To resolve this issue, we introduced a fallback to HLS allowing users to play video files with a slightly degraded experience, such as longer load times.

Additionally, we disabled a code optimization technique which fully restored HLS functionality for all users.

We are still working to restore full video quality. In the meantime, customers might still notice a degraded experience when playing videos in Slack.

We will be sharing more updates as they become available.
