Get the notice of Could not purchase “app name”. An unknown error occurred (8392) when updating apps on iTunes? Check this tutorial to quickly fix this iTunes error 8392.
Getting this error message daily: “Could not purchase “APPNAME”. An unknown error occurred (8392). If I keep hitting the “update all apps” button it will eventually download, but it’s very frustrating. I’ve signed out and back into Store, shut-down and restarted Mac (2016 iMac – all updates have been installed), but can’t get rid of this error. Not sure if related to this error, but when syncing both iPad Air 2 and iPhone 6 (both fully updated to latest software), to iMac/iTunes that all apps do not get updated on iPhone/iPad, I have to do this on the device itself, so lots of duplicated updated activities. I even set up the iPad as new, but the same problem persists. Any ideas?
