I updated my software to 5.0. I get notifications on my home screen when an app I downloaded through app world has an upgrade available, which is nice. However, when I try to upgrade it I get a message "(insert app name here) is not available for download from App World." I get the same message for anything I try to download through app world whether it's an upgrade or first time attempting to download. I have deleted & re-installed app world & it didn't work to solve the issue. Anyone know how to resolve this? Any help would be greatly appreciated.
