Yeah you would need to uninstall completely and then download from the app store.
You won’t receive push notifications as you would have been registered on pushwoosh under the sandbox app ID. This is why push notifications are a pain to test - once shown once the ‘allow push notifications’ dialog won’t show again, unless you uninstall, reset device, move the system time ahead one day, reset again and install.
I rather cleverly had the sandbox app ID in my final release code for the sending of push messages to specific devices, so I need to issue an update for that. I’m really treating this release as a beta for the engine and other games as it’s so difficult to get enough people to test before release.
