During dev time i've done some tests with app never releasedWhen i delete these apps, they move to "removed apps" and this prevent to reuse some App IDHow can I permanently delete an app so I can reuse an App ID?

What should be done when a Tester changes device? Testflight has a lot of constraints and limitations that waste a lot of time. I think that even Apple developers are always worse, like Google's... The concepts of usability, the things that are always needed at hand... ever heard of these things? Sorry for the outburst.. :(
