Meta AI in Italian stops right after wake sound – English works fine (Ray-Ban Meta Gen 2, iPhone)

Since the evening of Sept 26, Meta AI on my Ray-Ban Meta Wayfarer Gen 2 no longer works in Italian. After "Hey Meta" (or tap-and-hold on the touchpad) the LED turns on and I hear the wake sound, but the session closes immediately. Sometimes the answer starts ("Sono...") and is cut off after one word. It works about 1 time out of 15-20. No firmware or app update was installed when the problem started.

Key facts:

- With the Meta AI language set to English, everything works perfectly.

- Meta AI in Italian works fine in the iPhone app, both typing and voice. The problem only occurs through the glasses.

Already tried: re-downloading the Italian language pack, changing the Meta AI voice, force restart, unpair/re-pair (also from iOS Bluetooth), full factory reset, microphone troubleshooting toggle, disabling "Respond without Hey Meta", disabling wear detection, testing in a quiet room with no other Bluetooth devices.

Setup: iPhone, latest Meta AI app and firmware, Italy.

Is anyone else in Italy (or using other non-English languages) seeing the same issue since Sept 26?
