Very sad, based on current info, Samsung won't be introducing a setting in One UI 8 to disable both Wi-Fi and mobile data altogether for specific apps.
Current Samsung One UI Options
- In Samsung One UI 7 and likely One UI 8, you can manage data usage via *Settings* > *Connections* > *Data usage* > *Allowed networks for apps*.
- Options are still to disable either Wi-Fi or mobile data for specific apps.
How Other Devices Handle This
- *General Android Devices*:
1. You can manage data usage for apps via Settings > Apps > [App Name] > Mobile data & Wi-Fi.
2. By Seperate setting for network access with checklist.
