Numeric field classes issue on iOS mobile device

I have an issue on mobile iOS (iPhone 8), I try to pass a color classes on a disabled numeric field but my class is bypassed. I have tried on Safari, Perspective mobile app, Firefox and Chrome.

I want to diplayed my numeric with black color but it use the default gray disabled color.

Could you provide more info on your setup and exactly what you’re attempting to accomplish?

I only have a numeric field that I want to disabled to prevent value changes and want that the number stay displayed in black not in gray.

I only pass a style to the control. It work perfectly on desktop, but on mobile iOS the number stay gray.
