I've had to exit the dev program and re-sign up to get a code a few times, every time it goes to the app store after redeeming the code and it says successful it takes me to the app update/downloading page but nothing ever pops up. Help?
I have seen cases where it just takes time for the server to communicate to the Mac that it needs to show the download. It should appear eventually, but you can also try rebooting the Mac a few times and/or signing in and out of the App Store a few times to refresh it.
