I am trying to follow the instruction(https://island.oasisfeng.com/setup.html) and setup the work profile manually. Android 12. Insular installed from F-Droid

$ dpm set-profile-owner --user 0 --name Mainland com.oasisfeng.island.fdroid/.IslandDeviceAdminReceiver

Exception occurred while executing 'set-profile-owner':

Hi Guys! I had same problem. I was able to solve this issue. Just follow these steps:

1. Extract Island APK file.
2. Copy it to your Computer.
3. Install APK File using this command: adb install --user path/to/apk/file
