See Announcing Windows 11 Insider Preview Build 22581 | Windows Insider Blog for features, fixes, and known issues.
From the blog:
“Now that the Dev and Beta Channels are receiving the same builds, the limited window has opened for Insiders to switch channels if you wish to do so by following these simple steps:
- Open Settings > Windows Update > Windows Insider Program.
- Select Choose your Insider settings.
- Select Beta Channel.
- The next time you receive an update, it will be for your new channel.
IMPORTANT: This window will close once we release builds with higher build numbers to the Dev Channel. If your device stays on the Dev Channel and receives a build that is a higher build number than what is in the Beta Channel, you will have to do a clean installation of the released version of Windows 11 on your device to switch to the Beta Channel.”
