App Store Connect Error

I published a new iOS app recently and now I want to publish macOS app. The app is built in SwiftUI and macOS target is enabled using Mac Catalyst.

While costomizing my macOS app page in App Store Connect I can edit most of the fields except unchecking "Sign-In Required" checkbox and entering contact details. If I uncheck "Sign-In Required" checkbox and press Save I get this generic error: "An error has occurred. Try again later.".

Inspecting Console I can get this information:

{ appName: "appstore", payload: (1) […], eventKit: "logger", env: "PROD" } ​ appName: "appstore" ​ env: "PROD" ​ eventKit: "logger" ​ payload: Array [ {…} ] ​​ 0: Object { logLevel: "ERROR", message: "API Response Error: SAVE_APP_REVIEW_DETAILS_RESPONSE", url: "https://appstoreconnect.apple.com/apps/6739671911/distribution/macos/version/inflight", … } ​​​ componentStack: undefined ​​​ errorCode: undefined ​​​ logLevel: "ERROR" ​​​ message: "API Response Error: SAVE_APP_REVIEW_DETAILS_RESPONSE" ​​​ stackTrace: "status code: 409 --- api correlation key: <key>"

url:"https://appstoreconnect.apple.com/apps/6739671911/distribution/macos/version/inflight"

I contacted Apple support but they weren't quite useful and told me to ask people on forums... I don't believe this will help as clearly something is wrong with App Store Connect and the state of my account needs to be fixed on their end.
