This could be due to several things:1. You've switched from Android to iPhone or vice versa. The app has a lot of advanced features, and developing these could only be achieved through what is called 'native design'. This means that the Android and iOS versions of the app are developed independently of one another, and are two different products on the Google and Apple stores respectively. Hence your subscription also cannot be transferred from Android to iOS or vice versa. If you want to use the premium content across both platforms, you'll have to purchase the subscription twofold. However we offer a partial refund commensurate with the time left on your old subscription. To receive the partial refund, you must first subscribe to the WHM app on your new device, and then send us the receipt for both your old and your new subscription.2. You get 1 year free access to the premium features of the app when you sign up for the Fundamentals course, so if you purchased one year ago, that freebie may now be up.3. Google sometimes cancels a subscription when you reinstall the app shortly after purchase. Check your Google subscriptions to see if the WHM app is still listed there. If not, your money will have been automatically refunded to you, and you should be able to simply resubscribe and not have it cancel again.4. If you have multiple Google accounts on the same device, the app may not recognize your subscription. This is an issue with Google, which we have no control over. You may be able to get around it by uninstalling the app, logging into the Google account under which you have the subscription, and then reinstalling the app.
