!!!!! I FIXED IT WITH THIS!!!!!
1. Turn off apple intelligence
2. Change language and region to "United Kingdom"
3. Under apple intelligence > change language to "English (United Kingdom)"
4. Wait a few seconds until the option to turn it on appears and turn on "Apple Intelligence"
5. It should start downloading. If not just turn off "Apple Intelligence" and turn it back on. Or just wait I waited for about 5 min
After the 0% downloading disappears test it out by holding the lock button and glow should kick in. I recommend just wait here
Once I made that change, I was able to revert my Siri voice to American. However, I had to leave the iPhone’s Region set to the United Kingdom, which caused a few minor issues. For instance, I couldn’t type a dollar sign because it was now displayed as a British pound sign. Additionally, the click option was automatically set to 24-hour time instead of 12-hour time.
Despite these minor problems, it’s still a frustrating bug for an official release when the Beta version was functioning perfectly.
