When setting our workflow to use Xcode 27 beta 5, the pipelines fail with the following (from IDEDistribution.critical.log): 2026-08-13 11:01:14 +0000 [MT] Command line name "app-store" is deprecated. Use "app-store-connect" instead. 2026-08-13 11:01:14 +0000 App Store Connect request for store configuration failed for account Session Proxy Provider (Account "Session Proxy Provider": Unable to authenticate with App Store Connect (Error Domain=DVTITunesSoftwareServiceFoundation.DVTServicesSessionProviderCredentialITunesAuthenticationContextError Code=1 "(null)")) We're a multi tenant app (same code/project, multiple apps), so we've attempted this on two different AppStore Connect accounts, both resulting in the same error. Distributing from Xcode 27 beta 5 running on local machine works fine. For any Apple folks reading, I've filed a feedback (FB24286100) with links to multiple builds failing.
