Gemini in Polestar 3: "Strong authentication needed" for Gmail & Google Home?

​Hi everyone,

​Has anyone successfully used the Gemini app in their Polestar 3 to check emails or control smart home devices?

​Gemini works fine for basic queries, but when I ask it to read my emails or open my gate (which the old Google Assistant handled without issues), it blocks the request with the message: "I can't check your email because strong authentication is needed."

I've already tried hard resetting the infotainment, securing the driver profile with a PIN, and removing/re-adding my Google account, but nothing helped. Both iOS and Android phones behave the same way.

​Is this a known Gemini limitation on Android Automotive, or has someone found a workaround?
