Apple pay is not available despite all steps followed by the document

[acgacgacgacg]

Describe the problem
I followed the document here and setup merchant identifier, certificate, Xcode.
I changed the Stripe.merchantIdentifier in main to my own.
I tested on my iPhone. I added cards to wallet. I confirmed apple pay works in other apps.
I tested the example app on my iPhone but the Stripe.instance.isApplePaySupported.value is always false.

Expected behavior
Stripe.instance.isApplePaySupported.value should be true.

Smartphone / tablet

• Device: iPhone X
• OS: 15.6.1
• Package version: 5.0.0
• Flutter version 3.3.0

Additional context
Please tell me what makes Stripe.instance.isApplePaySupported.value false, so I can try to check small steps.

I figured out why.
JCB card seems not supported by apple pay with stripe, despite my account supports JCB.
