If you accidentally assign a device to the wrong person, you can simply reassign it to another person profile (or create a new profile).
1. Navigate to the incorrectly assigned device
2. Tap on the ⋯ on the upper right hand corner to view the device menu and select Assign Device to...
3. Select the appropriate profile to move the device to. You can also add a new person profile to your app at the same time!
4. Please note that any rules (Adblocking, Content Access, or Online Protection) will be reset to match the new profile
5. Your device will now appear under the new profile!
