App Store Connect not accepting Builds from Xcode 27 Beta 5

I keep getting the following error message when trying to upload a build to TestFlight using Xcode 27 Beta 5 (running under macOS 27 Beta 5):

This bundle is invalid. Apple is not currently accepting applications built with this version of Xcode. n/a (ID: 5CFNDXXPXFP2H4DVQPPGHA2YUE)

Is anyone else running into this?

Apple is not currently accepting applications built with this version of Xcode

The error message is pretty self-explanatory. So what's the issue?

Here's the feedback number for any Apple people who may see this: FB24262057

beta 5 was just published yesterday. May be there is a few days delay before appStore Connect accepts it.

I should add that I have another machine with Xcode 27 Beta 4 (running macOS 27 Beta 4) that I just tried and it works fine uploading a build to TestFlight. Unfortunately the call signature of one the APIs I'm using changed under Beta 5 (PrivateCloudComputerLanguageModel.supportsLocale(_:) so that's what's making this so urgent.

Yeah I came up against this, I happened to have a work computer that is still on 26.6 so I just built and resubmitted from there. I guess you could do like I did, or wait until September. Or rollback, I get that's a pain though.
