I have one app that is removed from sale individually but also still for sale in a bundle. Still,the option "Remove App" appears in "App Information" Section.
But as I pressed it, Apple says I cannot remove an app that is in an App Bundle. Well make sense. So I goto the app bundle and uncheck the "Cleared for Sale" box and save it. Then I open the bundle, where it says "Edit" I clicked on it and was able to remove the same app from bundle. Saved it and it brought me to main page of the bundle, and when I try to click Save there, it says
Error encountered saving or updating bundle: Attempt to add or remove apps from a bundle that does not allow editing.
