We're not calling the (new?) API to set the locale in any of the desktop embeddings currently.

Appears to not be a "random" locale, but instead the first one listed in our supportedLocales list

Same issue #52403 on linux but it returns null.

[stuartmorgan-g]

This is already marked as an issue for all three desktop platforms. None are passing locale information, as I said above.

[aliyazdi75]

Sorry, I've just wanted to mention issue here for any further information.

Has there been any progress?

I don't know if there is ways that can detect the dynamic locale setting change in each desktops (Linux/Windows/macOS), but I think that it is relatively easy to set the locale once when launch the app.

If there is no problem with the implementation that sets default locale setting at starting an app, I could support this issue.

Starting with just setting it on launch is fine. For systems where we get notifications about changes, we can add that later; it would leverage the code written for setting it at launch.

All three desktop embeddings are sending initial locale information now.
