On some iPhones and iPads, ibisPaint X closes right after it starts and cannot launch once it is updated to ver. 14.1.4.
We sincerely apologize for the inconvenience.

The fixed version (ver. 14.1.6) is currently under review by Apple, so it may take a little more time before it is released.
The same update (ver. 14.1.6) will also fix another ver. 14.1.4 issue that users have reported, where the brush and eraser icons are not displayed correctly.

If you need to use the app urgently, the following steps may resolve the problem.
*These steps only address the launch problem. They will not fix the brush and eraser icon display issue, so please wait for the release of ver. 14.1.6.
1. Open “Settings” → “General” → “iPhone Storage” (“iPad Storage” on iPad) → “ibisPaint X”.
2. Find the “Offload App” button. Before tapping it, check that the description below it says the app’s documents and data will be kept.
　*If the description does not say this, you are looking at a different button. Do not tap it. In particular, “Delete App” will also delete your artwork data.
3. Download the app again by tapping the ibisPaint X icon on your Home Screen or from the App Store.

We appreciate your patience until the fixed version is released.
