HiI'm having a problem where my apps are failing Archive validation for the app store with the message "App sandbox not enabled. The folowing executables must include the "com.apple.security.app-sandbox" entitlement with a Boolean value of true in the entitlements propertly list". It seems to suggest that my app is not sandboxed correctly. However, I've made no changes to its sandboxing since the last release and as far as I understand it, it's correctly sandboxed. By which I mean:• I have an appropriate .entitlements file• The entitlements file contains "App Sandbox" set to YES• App Sandbox is turned on under the target's "Capabilities"I thought it might be certificate related so I followed the instructions here (including the first of the "known Issues") but still no luck.Does anyone have any suggestions? I'm out of ideas!Thanks in advanceRob
