I am a newbie, made an app using Flutter (in VSCode on MacBook Air) - for iOS and testing the app works well, and trying now to upload the app as directed on App Connect. I registered the App with relevant information and images both for iPhone and iPAD, and then prepared the iOS release - using flutter clean and then flutter build iOS --release actions in Terminal. Following that as directed, opened iOS tab in VSCode, in Xcode (by right clicking and opening Xcode, and then made Archive file and it succeeded. Up to this level everything worked but the archive file is named as Runner (and not with the AppName - CFDisplayName in P.list and similarly the bundle ID is not as in the system and defaults to com.example.appName, and when I try to validate this file in Xcode, then able to correct name but can not change Bundle ID, and it remains as com.example.appName, and no matter what I do, the same error, "App Record Creation failed due to request containing an attribute already in use. The App Name you entered is already being used. If you have trademark rights to this name and would like it released for your use, submit a claim."
I can not delete the info I submitted on App connect site, and it gives an error it can not be deleted, as is use in App Store, when I have not submitted the App, only saved pertinent information and images on website.
I think I should n't have entered the app connect site first to register the app, and possibly let Xcode to validate and register app on app connect by default.
This is the first time I am trying to use the system, and would appreciate any help to correct this issue.
Thank you.
