Dear Apple Support,
We are encountering an issue with deep linking on iOS 26 when using Safari and App Store redirection. Below are the detailed steps to reproduce the problem:
- The app is not installed on the device.
- User clicks on a Branch link:
- For example:- https://qewed.app.link/99u88ef9f?uuid=88dbwh5ubd4b
- Safari opens and displays the fallback page.
- User taps on “Get the App”, which navigates to the App Store.
- User installs and opens the app.
Expected Behavior: The app should receive the Branch link parameters (in this case, uuid=88dbwh5ubd4b) upon first open.
Actual Behavior: The app opens successfully, but the uuid parameter is not passed to the app.
This issue seems specific to the Safari → App Store → App flow on iOS 26, as other flows behave correctly.
Could you please advise whether this is a known issue or if there are recommended adjustments on our side to ensure parameters are consistently delivered after App Store redirection?
Note: We are using Branch SDK version 3.11.0 (Cocoapods dependency)
Thank you for your assistance.
