I can't use cranberry plugins with CLI 5.1. I tried several times and of the several ways and I always get an error message when try to build an iOS app/game in the Intel XDK. I tried to use chartboost and revmob, the orientation lock as well. I've problem with the Google Analytics too. I want to use others ads services and I can't. Everything worked before the last Intel XDK updates.
When you say to leave addition.xml as it is, you mean as it is after export it to cordova, with references of the whole plugins, right? But if you are using the CLI 5.1 version you need to leave addition file blank, as I know. Can you give me more information about your app configuration in the Intel XDK?
I tested the orientation lock code that I posted in the forum and it works very for me, but only in CLI 5.1 version. I also tried the broswer action, but it not worked too. I don't know what I've to do anymore to fix it.
I have only one issue with audio in the iOS game: the sound only plays after the player touch the screen.
