Creating a new version fails in Web App Store Connect.
When you log in to the Web App Store Connect screen and enter a new version in an existing project, a red error screen as shown below is displayed and the new version cannot be registered.
"An error occurred. Please try again later. The version number was previously used."
It has been happening continuously since yesterday.
I hope you resolve this as quickly as possible. Currently, Testflight testing or distribution cannot be performed because the version cannot be created.
This phenomenon continues in both Safari and Chrome browsers.
The version you registered is a version you have not used before.
