Did a fresh install of latest 96.5 and can’t find these anywhere
Advanced mode
As part of Home Assistant 1.0 effort, we’re simplifying the default user interface. We’re doing this by hiding certain configuration options like the customize panel behind a new “advanced mode” toggle. You can find this toggle on your profile page.
Advanced mode is only available to admin users and is a per-user setting. Enabling it for yourself won’t enable it for other admins.
