Eager to hear this one! We consider using RevenueCat in our project since other providers rarely provide first-class KMP support. Kudos to the team and thank you for investing into the up-and-coming stack!

I'm already using revenue cat in my KMP app. My review is that revenue cat is currently the best solution for KMP the only downside I've faced is the documentation. Docs ain't clear for KMP but if you are experienced developer you'll be able to figure out things more easily

Is there a solution available to create a private library in KMP and also use it natively in both codebase along with CICD …..
