The #1 culprit for the stability of our app is the Fling SDK with crashes like the one documented below (I know the fling sdk is the culprit because it is the only sdk in our stack that makes use of Java's thrift ).
I heard the team was working on removing UIWebView references (UIWebView is being deprecated on iOS), so I wanted to make sure stability issues were being addressed as well in the next release.
There is no simple way to reproduce the crashes, they seem to appear randomly. More than happy to provide additional details if needed, just ask!
