Linking Lantern Pro Account to iOS device
First, download Lantern to your iOS device, then tap the settings cog in the lower right of the iOS screen to identify your support code.
From Lantern Desktop, navigate to Settings, then click "link device," and enter your support code to link devices. Pro accounts may link up to three devices.
Note: Free accounts may only have one device per account. To upgrade to Pro, select "Upgrade to Lantern Pro" from within the app.
