I'm getting this error when uploading archive of app to itunes connect for internat testing through testflight; "Failed to locate or generate matching signing assets" with subheading as "App id with identifier com.xx.xxx not available. Please enter a different string". I've successfully uploaded the archive to test flight twice already with the same identifier, and different bundle version string the second time. And third time, im getting this error all of a sudden. I even recreated the the provision profile, certificate, and app id. assigned the new app id to my xcode project and it's still giving the same error. Can anyone please help me out here.
