Has anyone set up and used Meta Ray-Ban Display + Neural Band in Japan?

Hi all,

I'm a developer based in Japan, and I'm thinking about getting a Meta Ray-Ban Display + Meta Neural Band (bought in a supported country such as the US) to use here.
Japan isn't on the official list of supported countries, so I'd love to hear from anyone who has actually tried it in Japan, or in any other country that isn't officially supported.

If you don't mind sharing:

1. Where did you buy the glasses, where did you do the first-time setup, and when (month/year)?
2. Did the setup (pairing and activation in the Meta AI app) finish without problems?
3. Which features worked, and which didn't?
   - display / Neural Band controls
   - camera (photos and video)
   - Meta AI, navigation, etc.
4. Have you turned on Developer Mode in the Meta AI app, and tried an app built with the Device Access Toolkit (camera, display, or Neural Band input)?
5. Did anything stop working later on, for example after a firmware or app update?

Even a short reply would really help. Thanks in advance!
