I initially had same error as noted in this forum http://forums.coronalabs.com/topic/37868-unable-to-connect-to-internet/ so I updated corona to 2013.1228 accordingly and I don’t see that network error msg anymore
However, I wanted to test this expansion file by manually loading it using ddms and when I did, I see an error msg popup on download screen saying “Not market managed”
I’ve manually put my obb file into Android/obb/<my.packakge>/main.1.my.package.obb.
This is my android app so I’m not sure where I messed up.
