I am using multiple Crashlytics.log() commands, for example:
Crashlytics.log()
Crashlytics.log(\"This is message 1\"); Crashlytics.log(\"This is message 2\");
I am using the Crashlytics log system and I can see more that one log. In fact I can see all the logs that I've added to the app before the crash point.
My guess is that your app has a crash before your "message 2" log line.
