For anyone who is considering building a mobile app using a cross-platform or hybrid framework such as React Native, Ionic, or Kony, keep in mind that debugging a memory leak can be very difficult!  I've been tracking down the source of a slow memory leak that's causing the Android version of our Kony app to crash if the user camps out on a particular screen for an hour or two.  The logcat backtrace and tombstone info really just tells me "something went wrong when the Kony API was called".  One of many tradeoffs with cross-platform frameworks.
