Hi, thanks for the reply.
So I setup the app page and the app specific password. I guess I do not have the correct bundle name. So wich names have to match? Is it the package name in B4I? So where in the App Store Connect and in the B4I settings do I have to enter the same name?
Also I get an error when uploading "This bundle is invalid. The IPA format requires a top-level directory named Payload, containing only a .app bundle and optional plugins in a Plugins directory".
