Hi,
These post do not cover the "internet" access. Is it not a case of setting "Internet Acsess" to auto in your Unity publish settings?
If it is already set to auto, then, all *www* actions have to go. all Network actions have to go as well ( the network folder in the PlayMaker actions folder")
also, do you have other frameworks? you need to check them out as well, maybe they trigger the use of internet flag as well.
bye,
Jean
