Branch Link Parameter Not Passed to App on iOS 26 when come from Safari

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:

  1. The app is not installed on the device.
  2. User clicks on a Branch link:
  3. For example:- https://qewed.app.link/99u88ef9f?uuid=88dbwh5ubd4b
  4. Safari opens and displays the fallback page.
  5. User taps on “Get the App”, which navigates to the App Store.
  6. 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.
