Can not upload using Xcode 26 Release Candidate

I just downloaded the latest Xcode 26 RC version, after the Apple Event.

However, it prevents me from uploading the app to App Store Connect. I was able to upload and set up public TestFlight using the Xcode 26 beta version, and have been doing that for weeks. But the RC doesn't allow me to upload?

I've also updated MacOS to 26 RC as well, not sure if that's an issue.

Update: It works now.

I have been trying all morning with Xcode version 26.0 (17A321), on macOS 15.6.1 (24G90). And I'm having the same issue.
