Hi, I'm following the guidelines for deploying a native app and i'm stuck at the prepare command; i'm getting the indicated warning (step 4.3 / https://docs.mendix.com/howto/mobile/deploying-native-app) which indicates that the app center configuration has failed. As is part of the app centers security policy. The solution states that I should navigate to the app center and select my newly created app. The problem is that my app doesn't show in the app center. Any suggestions?
