Thank you for your kind and thoughtful response. I would like to confirm once again. So can I assume that iOS 26 only provides an API to jump to the [Settings app] path? Will attempts to jump to other submenus in the system settings be redirected here by default?

[quote='871245022, DTS Engineer, /thread/805248?answerId=871245022#871245022'] If you attempt to navigate to specific Settings pages by opening undocumented URLs, you’re exercising implementation details. The exact behaviour you get isn’t documented and may change from release to release. [/quote] Sorry, I would like to confirm again. We found that not only did the redirection to the [Settings app - Personal Hotspot] not work, but redirection to the [Settings app] itself is also ineffective. Does iOS 26 completely prohibit the use of private APIs? And is the only recommended method for opening the [Settings app] now the use of [UIApplicationOpenSettingsURLString] API?
