We're making a new mobile app with React Native. Can I split up report suites, one for iOS and one for Android with React Native? If so, how would I do that with best practices?
You could likely use OS type iOS and Android as you build the VRS segment. I've moved this discussion topic to the Analytics forum. Pros here will be able to help you with additional questions.
Assuming that you are using 1 Launch property to setup both iOS/Android apps - to fork data by platform you'd need to change configuration client side to accomplish this. However, instead of splitting report suites - have you considered using Virtual Report Suites?
