Any update on this? I would love to hear from the team if there is any way that at least some of the points I was proposing can be addressed. Thank you.

I have set the language for Apple Inteligence and for Siri to English (US) before, but I haven't tried the region. After setting the region to US, it is working. Thank you for your help. Is this limitation going to be also in the shipping version? I expect many customers around the world to be using English but not having US as their region.
