I develop with React Native in my day job and I'm observing all the UI changes that are happening in the systems. So far there aren't many problems with the differences, for example in the alpha version of Android 12, Google introduced a sparkly ripple effect (they eventually removed it again). But this change was automatically propagated to all our interactive components of our React Native app, no changes to our codebase necessary. And this is the case for many other changes, since React Native uses actual native elements.
