I like how easy it was to learn, but also dislike some of its limitations (I have issues generating complex forms).
The documentation can be frustrating at times! Make sure your using one specific version or make backups in case something goes wrong - especially if this software has been around for many years!! My first thought when looking into creating an MVP website through React Native would be "This sounds too complicated". But after working closely together we had no problems getting started right away and were able to build out our front end quickly without going back-and forth between native android code & javascript/react stack over time.
