Lab-Ally has run into the same bug and it's causing us some pain. We can manually toggle the switch in local network to on, but if the computer restarts it will "forget" that this permission was granted. The user has to toggle the switch off and on again to restore access. Also, for us this only seems to affect accounts migrated to sequoia on M4 from Intel Macs with a prior OS. NEW Mac admin accounts made on the same sequioa machine are NOT affected.
