Keyboard does not appear in SFSafariViewController on iPad (App supports iPhone only)

Hello,

I am experiencing an issue related to SFSafariViewController during App Store review, and I would like to ask whether this could be an OS-level behavior or a known issue.

App context

Our app supports iPhone only

During App Review, the reviewer tested the app on an iPad

The app was rejected because the keyboard did not appear

Issue description

The problematic screen presents a sign-up web page using SFSafariViewController

When tapping the nickname input field:

The keyboard area appears (the layout shifts as if the keyboard will be shown)

However, the actual keyboard does not appear

Reproducibility

We tested this issue on our own physical devices and on iPad simulators with the same app configuration

However, we are unable to reproduce the issue in either environment

What we have checked

The web page uses a standard HTML <input type="text">

There is no custom keyboard handling or keyboard-related logic in the app

The app simply presents SFSafariViewController with a URL

Locale-related question

The URL includes a locale parameter (e.g. LOCALE=US)

Could the app’s locale, system language, or region settings affect keyboard behavior in SFSafariViewController?

Is it possible that a specific locale or language configuration on iPad could cause the keyboard to fail to appear?

Questions

Is there any known issue or OS-level behavior where the keyboard may fail to appear in SFSafariViewController on iPad?

Could this be related to:

Locale / language / region settings

iPad multitasking or keyboard modes

External keyboard state

Specific iPadOS versions

Are there any recommended workarounds or defensive implementations for this scenario?

Any insights or similar experiences would be greatly appreciated.

Thank you.
