Unity Crashlytics for iOS and android not working

Crashlytics Dashboard for iOS does not display line number or class name, and for android crashes it doesn’t report at all, just the example code provided by crashlytics team works.

Is there a way to make crashlytics for unity work with accuracy?

Line number and file name of managed code are only available in development builds. In non-dev you’ll get class and method in stack. Android works, maybe you’ve missed something during import plugin? Where did you download it?
