Why are you using Continue with Apple to activate the subscription?

Continue with Apple is the fast, easy, secure, and private way to purchase and sign into apps using the Apple ID that you already have. Instead of using a social media account where they track you, or filling out forms with an email address and creating yet another password you have to remember, you’ll just tap the Continue with Apple button, confirm your information, and sign in quickly and securely with Face ID, Touch ID, or your device passcode.
