"Cannot complete action to accept iCloud terms: I've tried repeatedly to accept new iCloud terms on Apple devices and receive the error message "Cannot complete action." Devices are all current with latest OS 17 version software (but not OS 18). So far there's no problem continuing to use iCloud across devices. What's the fix to accept new terms?"
