Anyone ever see a crash w/o a stacktrace in the Android app after introducing Kotlin to an app? First time I've seen this and not quite sure where to start in fixing it except for undoing everything I did...
The no stacktrace thing is what has me puzzled. Proguard is disabled so it's not that causing it..and that should dump useful stacktraces about missing stuff.
