  • Logging: In addition to setting the variables PubnubLogLevel = LoggingMethod.Level.Info and PubnubErrorLevel = PubnubErrorFilter.Level.Info you also need to add a "define symbol": ENABLE_PUBNUB_LOGGING for each of the platform you want to enable logging. This setting is available in the Unity Editor: File-> Build Settings -> Player Settings -> Other Settings -> Configuration -> Scripting define symbols. After you type ENABLE_PUBNUB_LOGGING in it do remember to press return with the focus still in the text box or your setting will not be saved.
