I uploaded a new build of the app and that seems to have resolved the issue. 🤷‍♂️

I'm having this issue with 1 application in TestFlight as are my users. Feedback FB22349590

Looks like this is working as of Ventura!

Very sorry, I did not see this reply until today: import Foundation extension Locale { var voiceLanguage: String { (languageCode ?? "") + "-" + (regionCode ?? "") } }

I'm having the same issue with a mac app that we have in the app store. Would be nice to be able to use the new TestFlight feature for testing since it's an in app purchase app.
