Is it possible to change Payment Method without canceling Subscriptions?

1. There was an offer for a free one-month subscription, so I subscribed.

2. After some time, I wanted to change my payment method.

• Naturally, before changing the payment method, all subscriptions must be canceled.

3. I went to cancel the subscription, but I was surprised to find that there is no option to cancel.

4. Please do not send me the routine links that direct you to the app store to cancel the subscription because I have already tried everything.

5. The option to cancel the subscription is not available!

6. If I add another payment method, the amount for the app will be deducted immediately.

• I tried adding a card with no balance, and an attempt was indeed made to charge $9.99, which is the app’s price.
