Your toggle configuration looks correct. This is a known platform-specific issue where iOS doesn't display the toggle language properly even though Android works fine.

iOS Google Home app doesn't correctly render the name_values with lang attributes for toggles, even when the SYNC response is properly formatted.

What to check:

• Verify your iOS app is updated to the latest version
• The lang field should use ISO 639-1 codes ("de", "en", "ja" are correct)
• Make sure the name_synonym array has at least one entry per language

Since this is an iOS-specific rendering bug, there's no immediate fix on the integration side. The toggle will still function correctly via voice commands in the appropriate language, it just won't display the localized name in the iOS UI.

File a bug report through the iOS Google Home app so this gets prioritized for the iOS team.
