It is the duplicated app connection problem. When I do a custom install (duplicate) of Angry Birds 2 everything installs fine and I get two installs of the app. However, when I open the hacked app everything loads but as soon as it's finished signing me into IOS gods I receive a "Connection Error" and everything stops there. If I delete the original app, and just install the hacked app everything works fine.
So my work-around to date is as follows: Save my progress and uninstall the unhacked app and install the hacked app and load up on what I need to continue playing. The hacked app does not have full access to all parts of the game so then I have to save my progress and Delete the hacked app and reinstall the original unhacked app so I can continue playing. As you see this is time consuming and getting annoying.
When I paid for the IOS gods app+ and VIP access it was with the assumption that I could have both apps on the same device. I would just use the hacked app, but certain (important) parts of Angry Birds 2 are not accessible through it, so i need to have duplicate apps. I don't mind putting the hacked app on an old iPhone to use there and keep the original on my iPad which is why I requested to transfer the UDID.
Does all this make sense?
Cheers
