Hi folks, had the same question, my solution is similar to the above prescribed. The reason is not a missing App Store Connect menu point (like many questions in the net suspect), but the bundle ID for both the IOS version and the MacOS version. Even if I managed to give the MacOS version a different ID, I could not delete the app`s separatly. So I pushed another IOS version (as stated above) with is similar name giving a cheap inApp purchase price for a transfer time. Ulix

Hello, adding a question to this answer "You can delete a platform if a build has never been uploaded for the platform you wish to delete. Additionally, at least one existing platform version needs to be in an editable app status. If the criteria is met, hover over the platform you wish to delete and click the delete button (–) that appears to the right of the platform." Is it possible to delete a platform if a build was uploaded and the app as macOS version is for sale in a bundle App-Id? Thanks for any help Uli
