I updated to iOS 18.4 beta developers and set the language of Siri and the phone to Spanish (Spain). Apple Intelligence says downloading but it never finishes. It has been connected to the wifi and plugged into the power for more than 12 hours.
Apple intelligence (spanish) in iOS 18.4 don’t download
Same issue in Germany. It did Download for an iPad M2 but does not on my iPhone 15 Pro.
iOS 18.4 is currently a beta, so we'd appreciate if you could take the time to using the Feedback Assistant app to report any issues you're having, such as with the download of Apple Intelligence.
