I updated my iPhone 15 Pro to iOS 18.1 beta the last Wednesday, since that day always remains stucks in joined waitlist with the following message: Support for processing Apple Intelligence models on device is downloading.
The troubleshooting steps that I did were: Restart de iPhone Change WiFi connection I made sure to have US language and US region Have Siri in US language Erase network settings Erase all settings Erase all content and settings
Issue persists
I'm in Costa Rica and also my Apple ID but I don't think that I need to switch the Apple ID region to USA because my MacBook Air M1 Apple Intelligence was installed successfully
