Now that you have redeemed your Premium gift promo code, all you need to do is make sure the Premium subscription you previously purchased through your mobile app is canceled. It is important that this subscription is canceled, so that you are not continually billed through the app store.
You will still have Premium for the full length of time that was paid for through the app store, plus the length of the gift Premium you just redeemed.
If you previously purchased Premium through your Android app, you will need to cancel this subscription in Google Play. Click here to be re-directed to your subscription management page, where you can cancel your Google Play subscription.
If you previously purchased Premium through your iPhone app, you will need to cancel this subscription in iTunes. Click here to be re-directed to your subscription management page, where you can cancel your iTunes subscription.
Once you have canceled your mobile subscription, there is nothing left for you to do but get out there and have fun! Thank you for being Premium!
