- Use a private/incognito window to test a clean session.
Mobile devices:
- Ensure the VPN permission is granted for the app in settings.

- Reboot the router after making changes to verify they take effect.

DNS, leaks, and kill switch essentials

Gaming:
- Look for servers with the lowest latency. Narrow the server pool to nearby locations and test ping in-game.
