One of my Mac, currently running macOS 13.4 Beta 3 don't see recent beta and RC.
my developper account is not identified as developper on this Mac ( only display Public or consumer beta)
Same account on another Mac is ok. sign-out / sign-in in iCloud change nothing
Will try to revive the Mac with Apple Configurator to update but it's not ideal.
The only "exotic" setting is the Mac is enrolled on an MDM ( who don't restrict beta)
