Xcode 16.2.
When calling openURL:options:completionHandler: when in the simulator for a link in the app store (for example: http://itunes.apple.com/us/app/slidewords/id503737864?mt=8) behavior is fine for simulated iPads, not for simulated iPhones.
When the simulated device is an iPad, the call correctly opens the app store link. When the simulated device is an iPhone, an error message "Safari cannot open the page because the address is invalid."
Note: the call works on an an actual iPhone (iPhone SE 3rd generation, unsure about other devices).
