I got this error when uploading my build in iTunes Connect:
iTunes Store operation failed.
This action could not completed. Try again.
I tried, and tried, but nothing.
The steps I have done are:
XCode
-> Product
-> Archive
-> Upload to App Store
-> Error
For programming, I use C# and I use Unity to build for XCode.
There are no errors when I compile the build; the error happens only when I upload it to the App Store.
