Sadly the UK has also been hit with the fallout of the EU's AI Act, and we are also not able to have Advanced Voice Mode.

I have just cancelled my Plus subscription because of this, and wrote to OpenAI to explain that the EU's AI Act does not apply to the UK.

Hopefully OpenAI will soon release this feature to European nations that aren't burdened by the EU's low-quality and overly-aggressive technical regulation

Sad to see. Things like this are why there isn't as much AI innovation in Europe.
