I want to change my Insider Settings to Beta from Dev. However, the option to switch it is greyed out. I contacted Microsoft Support already and they referred me here.
To lower the channel, you need to perform a clean installation of the Beta version, which will remove everything. Unfortunately, this is necessary because the Dev. version has a higher build number and cannot be overwritten with a lower Beta build version (this policy applies since Windows11 in Insider :)
