Tips

  • Shortcuts: Create a Siri Shortcut to connect or disconnect with your voice
  • Background refresh: Keep background app refresh enabled so the app stays up to date
  • Low power mode: VPN may disconnect in Low Power Mode. Disable it or use auto-connect

Troubleshooting

  • “Cant find app in App Store”: Some regions block VPN apps. Use the TestFlight link or change your Apple ID region
  • “Wont connect”: Try a different server from the list
  • “Keeps disconnecting”: Enable auto-connect and keep the app open in the background
  • “Subscription not loading”: Check that your subscription link is still active in your dashboard
