I am working on a new app which has never been published to App Store, but the builds were pushed to Test Flight in past with support for both iPhone and iPad.

I need to drop iPad support and made necessary changes in app configuration under Supported Destinations and Deployment Info. But even after this, when I run the app on iPad via side load (i.e. running app on iPad via Xcode), instead of throwing an error, iPad still launches the app in iPhone format/size.

Attaching screenshots which shows app config and how the sample app looks in iPad. Are there any other changes that I need to make to only support iPhone?
