Regarding the setup of emails to customers on March 19, 2026

Thank you for your continued patronage of Kantan Subscription.

We have released a fix on March 19, 2026, at 13:00 to address an issue where some customers' email settings were not being reflected.
From now on, customers will not be notified by error email unless the box for "Settings => Send notification email to customer upon payment error" is checked.

Thank you in advance for your cooperation in the above.
