Should I Use the Same UI Kit on Web and Mobile? [on hold]

I am wondering how consistent the UI design should be across web and mobile. I want to use React for the web and React Native for mobile, but Bootstrap isn't available for React Native. The only library that is available on both is Ant Design that I've found. Can I just use Bootstrap on web and use something else on mobile? I know how to style components, so I could also just not use a UI kit, but I worry about how consistent I can make things look. I have no formal education in UI design.
