After updating my system from High Sierra to Mojave I am getting an error of " the transport has been detected as having stalled and has been aborted" while uploading App to the Appstore.
Why I am getting this issue, please do help I am stuck with this trouble?
Hey i am assuming your are using application Loader. Please go to Settings -> Advanced and uncheck DAV option. After that try to uploads.Its worked for me through application Loader.
Also check for your application Loader update if you have any.
I hope it will works !
