We have identified that, under certain conditions, it was possible to repurchase a Premium Membership on the purchase page even when the customer already had an active Premium Membership subscription.

Below, we explain how we plan to address this issue.

(1) Resolving Currently Active Duplicate Purchases

For customers who currently have duplicate purchases, we will cancel the duplicate subscriptions and process refunds using Microsoft Store's functionality.
Please note that only the duplicate subscriptions will be canceled, so your Premium Membership service will continue without interruption.

No action is required on your part regarding this matter (*).

(*) Depending on the timing of your subscription renewal, you may receive a notification email from Microsoft Store.

(2) Compensation for Past Duplicate Purchases

In ver.14.0.3 released on 2026/05/25, we have added a function to display a notification regarding compensation procedures for customers who were previously affected by duplicate purchases.
If duplicate charges have occurred, a notification regarding the compensation procedure will be displayed when the app is launched.

We sincerely apologize for the inconvenience. To eligible customers, we kindly ask that you update the app to the latest version, review the notification, and proceed with the compensation procedure.

(3) Measures to Prevent Recurrence

We will fix the known issue that allowed duplicate purchases to occur.
Additionally, we will implement a system that automatically detects and cancels any duplicate purchases should they occur in the future.

We will continue to update this notice with the latest information on our response.
We once again deeply apologize to all affected customers and kindly ask for your patience until the matter is fully resolved.

Thank you for your continued support of ibisPaint.
