Twitch streams are live events and are not recorded for later playback.
However, some streamers may choose to save their streams and make them available for replay on their channel.
If a streamer has saved their stream and made it available for replay, you can watch it by navigating to their channel and selecting the “Videos” tab.
From there, you should be able to find the saved stream and watch it.
Keep in mind that not all streams are saved, and even if a stream is saved, it may not be available for replay.
Additionally, saved streams are typically only available for a limited time, after which they are deleted.
If you are unable to find a saved stream on a particular channel, it is likely that the stream was not saved or is no longer available for replay.
There is however a slight workaround to rewatching a small snippet of a live stream if you missed it and that is by using the clip functionality.
Granted this will only give you access to the previous minute and 25 seconds from when you hit the clip button, it’s the only real current method that works to rewind a twitch stream.
Hopefully, in future, there is a better way to do it.
