This action could not be completed. Try Again (-22421)

Question

I am trying to upload an Apple TV App to the App Store for testing purposes, but I got the issue:

This Action could not be completed. Try Again (-22421)

as in the below image:

So what can I do?

Answer 1

This happens because Apple's servers may not be working correctly. Just wait and try later or next time. It will work for sure eventually.

Answer 2

Just try exporting the iPA file and then upload that exported iPA file with application loader. It will solve your problem.
