Custom_FirebaseMessagingService.java contains the following code:
boolean isLeanPlumPushNotification = (remoteMessage.getData().containsKey("lp_version"));
to check if push message is intended for leanplum, but leanplum SDK has another check inside: messageMap.containsKey("lp_message").
So, it looks like the sample and the actual SDK code are not aligned.
Which of the keys should I use?
