Created attachment 472634 [details] Screenshot of the same notifications on Android (with custom icon) and iOS (with default app icon) MDN lists the Notifications API's `icon` option as supported in iOS Safari 16.4 but the notifications always show the default app icon (declared in the manifest). I used Peter Beverloo's excellent Notification Generator and some additional local testing to confirm my findings: https://tests.peter.sh/notification-generator/ MDN compat table: https://developer.mozilla.org/en-US/docs/Web/API/Notifications_API#browser_compatibility MDN `icon`: https://developer.mozilla.org/en-US/docs/Web/API/Notification/icon Screenshot of the same notifications on Android (with custom icon) and iOS (with default app icon) attached.
