What is twitch commercial break in progress?

As an AI language model, I don't have access to real-time information about Twitch streams. However, I can provide some general information about Twitch commercial breaks in progress.

When a Twitch streamer runs a commercial break, viewers will see a message that says "Commercial break in progress" and a countdown timer indicating how long the break will last. During this time, viewers will see pre-roll ads and may also be served mid-roll ads during longer streams.

Twitch streamers can choose to run ads manually, or they can opt-in to Twitch's ad revenue-sharing program and have ads run automatically at set intervals. These intervals can be customized, with options ranging from one ad per hour to three ads per hour.

While commercial breaks may interrupt the viewing experience for some viewers, they provide revenue for streamers and help support the Twitch platform. Some viewers may also appreciate the opportunity to take a quick break during longer streams.
