No keyboard triggered on Iphone

Hi there,

Testing on Iphone, when triggering the motive search the input field is not focused and the keyboard does not appear until I click again on the search input.

This means a customer clicks the search icon and the motive modal appears but they have to click again on the search bar to trigger the keyboard.

Is this expected behaviour on an Iphone? The trigger works instantly with a keybaord on android.

Many thanks,
