After updating to macOS 14 I am unable to sing in to a test Sandbox account in the App Store app.
Steps to reproduce:
- Open macOS "App Store" app
- Go to settings (CMD + ,)
- If already a sandbox account is listed in the bottom section then sign out
- Click "Sign In" button in the bottom section
- Follow authentication prompts
Current behavior:
Authentication completes, but the state of the bottom section does not change. Only the "Sign In" button becomes active again.
Expected result:
Authentication completes and the bottom section displays current Sandbox user.
