Yeah and they announced this to be part of the free version. No mention of Gemini Advanced inside the launch blog post:

So yeah... I'm certainly not paying for Gemini Advanced if Gemini alone is already showing me that it's in fact not capable of what Google advertises to me. I don't want to pay money for a product which has bugs or incomplete feature rollouts and not getting the value for my money like other users perhaps. That's just fucked up.

I get exactly the same error in Gemini Advanced. And I am very much in the US (and Google seems to understand this, it identifies my location accurately).
