Crestron app for iPad
I’ve downloaded Crestron for iPad. It is free but has in-app purchase (upgrade). I am unable to upgrade app with error message:”Your Purchase Could Not be Completed, contact itunes support www.apple.com/support/itunes/ww/“
I am in Serbia with Croatian Store (there is no store for Serbia).
I tried to contact support but there were no response.
What should I do?
