### 3/5 — Crash on iPadOS latest version

*2026-04-09, version 1.1.4*

After updating to the latest iPadOS, Safari crashes immediately when I activate the extension.

This issue happens every time, and I observed similar behavior with other video speed extensions as well.

It seems related to a change in Safari or iPadOS.

I hope this can be fixed soon.
