When I add a ToolbarItem to my ContentPage, it works fine on Android. But on iOS, the menu text is invisible though clickable on iOS. What’s going on? Image icon still works fine on Android. But the icon is still not visible on iOS. Tested on iPhone SE 2nd gen.
The following ContentPage was generated by VS 2022. I just added ToolbarItems part.

    <ToolbarItem Text="Test" Clicked="OnTestClicked" />
</ContentPage.ToolbarItems>
