SkieCan I apply a policy or app list to a whole group at once?
Yes. Attaching a policy or app list to a group applies it to every device in that group together, so you never set tablets one by one. Each device picks up the change on its next sync, or straight away when the screen turns on or the internet returns, and you can watch compliance rise as devices apply it.
The group is the working unit. When you attach a policy or app list, the change is for the group as a whole. A class of forty tablets, a hostel floor or a delivery team all move together. There is no per-device checklist and no way to end up with half a class on last week's rules by accident.
Devices receive the change when they sync. Skie runs a background service with a watchdog, reports presence about every four minutes, syncs instantly when the internet comes back, and re-checks when the screen turns on after being stale. Rules are cached, so a tablet in a basement classroom still follows what it last received.
Before you attach, use the impact preview to see how many devices will change. After you attach, the compliance score and the 'on latest policy' share in Insights tell you how many have actually applied it. Because each protection is read back from Android after an apply, the number reflects reality.
A practical tip: for a one-off need, such as an extra app for a single lesson, attach the change to the group for the lesson and remove it afterwards, or use the extra-apps option on a schedule. For anything long-lived, fork the policy first so you do not disturb other groups that share the original.
