Shopify order payment will be changed after 72 hours using Convenience Store Payment ?

[Ethan_sh]

I can not find the document about this case. Because, I am implementing the feature related to CS Payment and Shopify Order Payment Status. Due to Shopify, After 72 hours have passed since the purchase was completed, the payment status will change on Shopify Admin screen regardless the payment deadline set in CS Payment portal. The status will become "Expired". It's right ?

Please help me ~~~

Thank you.
