Summary REGRESSION (iOS 26.1 beta): Web apps do not cover edge to edge
The Florist
Reported 2025-10-09 07:06:17 PDT
Created attachment 477035 [details] flowery.app on iOS 26 and 26.1 For web apps added to the Home Screen, `viewport-fit=cover` no longer enables the edge-to-edge layout [1] in the portrait orientation. While the safe area insets are still respected, the top inset is now filled with a solid color, as shown in the attached screenshots. This regression was probably introduced by the fix for the `position: fixed` bug [2] on iOS 26.

Thank you for the report! It's been determined that this is actually an issue in Safari, not in WebKit, so this will continue to be tracked by Apple internally.
