Apple Intelligence download issue

Yesterday after updating to iOS 18.1 I joined the Apple Intelligence waitlist on my iPhone 15 Pro. About an hour later I noticed that it had the message "Support for processing Apple Intelligence on device is downloading." A day later it is still displaying the same message. I have strong wi-fi, I'm plugged in to power with full battery, and there are 750gb available in storage. From what I have been able to find online, this isn't the typical user experience and that it probably isn't going to complete the process at this point. Any advice on how to proceed and get Apple Intelligence installed and working would be greatly appreciated.

Strange - had this issue for a few weeks and couldn't resolve it. I tried changing languages, rebooting, many things - never could get it to work on my mac.

However, thought I'd try it again - switched Siri language to Canadian english (with AI off) and then turned it back to American English and turned it on and it worked.
