Question

1. I regenerate all of the certificates, update the version number of the app

Answer 1

In my case we contacted apple and they said the issue is that it seems that we don’t have a correct certificate generated on developer.apple.com. We use Xcode automatic signing management. I refreshed correct profiles, rebuilt and I could submit successfully.

Answer 2

I had the same problem. Tried from different system and it got saved

Answer 3

In Prerelease section the status of your build should not be "Processing". Just wait some time (10-20 min) after build upload, and it will be ready to use.

Answer 4

I got the strange but working solution. I had tried submitting the app using Safari browser but it didn't work and showed same error. Submitting the App using Chrome worked for me in the first go...

Answer 5

I had the following issue when submitting a build which was uploaded couple of days ago for test flight testing. Then figured out that the provisioning profile of the application has expired so I renewed the prov profile and downloaded and re-archived the application (by increasing only the build number ) and uploaded and submitted it. And it worked like a charm.

I guess apple need to be specific of these error scenarios
