Subscription Manager funktioniert nicht

Keep track of your subscriptions and recurring payments, capturing data such as the name of the subscription, what it is for, the amount of the subscription, due date, currency, and even special notes like when you want to cancel it.  Automatically see the total amount of money you spend on all subscription on a yearly, monthly or weekly basis supporting multiple currencies.  The Subscription Manager app is a convenient way to track your subscriptions and expenses.  If you want to start, cancel, pause, or modify a subscription please contact the service directly.  Note: Subscription Manager cannot start, cancel, pause, or modify a subscription for you.  Sort subscriptions in a number of ways, pick from tons of currencies in the app, create custom categories to group subscriptions, change the theme or icon of the app, and more.  You can even archive a subscription if you want to pause your subscription and pick it up at a later time.  You will not be able to cancel the subscription once activated.  Your subscription will automatically renew unless canceled at least 24 hours before the end of the current period.  Get notifications (Opt-in only) when subscription bills are due.  Group subscriptions by category so you can see the amount you spend in each category.  View your subscriptions and expenses right on your home screen or just ask Siri about your remaining expenses and more!  Subscriptions will be charged to your credit card through your iTunes account.  After purchase, manage your subscriptions in App Store Account Settings.  You can select the option to see the total, remaining, or average amount due.  We believe privacy is a human right and do not collect any user data.
