Maybe it’s related to the issue listed in the release notes
- For languages other than English (US), Apple Intelligence support requires Siri to be enabled. (144092696)
Workaround: Enable "Talk & Type to Siri" to enable Apple Intelligence features. For "Talk to Siri", one of the following options must be selected: "'Hey Siri'", "'Siri' or 'Hey Siri'" or "Press Side Button for Siri".
Or I just didn’t wait long enough for a potent download of the AI modules
Two things definitely aren’t working without an US AppStore ID:
- iPhone mirroring and
- Call Recording
What seems still odd to me.
