If you already have Lookout Premium and want to upgrade to Lookout Premium Plus, you will need to cancel your Lookout Premium subscription first, then upgrade to Premium Plus.
Because your Lookout payment is controlled by Apple, you will need to cancel your subscription through your iTunes account. Here's how:
- Open the Settings app on your device
- Tap on your AppleID
- Tap Subscriptions
- Select Lookout
- Tap Cancel Subscription
Once your subscription expires, you can choose to upgrade to Premium Plus from within the Lookout app.
