[Resolved · Residual impact remaining] Bug where text entered with certain fonts may not display in image editing on the iOS app (Last updated: 2026/08/10)

Overview

In certain versions of the app, editing images using specific fonts caused the following issues.

• Text that had already been added would not appear in the image editing screen, and saving the image in that state would cause the text to disappear.
• Even when adding text from the image editing screen, text using the affected fonts would not appear on screen and would not be displayed in the saved image either.

Date and Circumstances of Occurrence

From the release of Ver.7.2.3 on June 1, 2026

A fixed version (Ver.7.4.2) has since been released and is now functioning normally.

Scope of Impact

• Mobile app versions affected: iOS app Ver.7.2.3 through Ver.7.4.1
  Occurrence may vary depending on your device and OS version.

For Customers Using the iOS App

A fixed version has been released. Please update your app to Ver.7.4.2 or later.

Regarding Images Saved in an Environment Affected by This Issue

Opening the image editing screen and saving again with the latest fixed version of the app (Ver.7.4.2) will cause the text to reappear.
As a result, unintended text may become visible on screen.

Since it is difficult to identify all affected images, if unwanted text appears during re-editing, please manually delete it and save again.

We sincerely apologize for any inconvenience this may have caused.
