Weather data update mostly haven't work on Wayland.
OS: Arch Linux with GNOME 40 now. I installed this extension from its page on the official GNOME Extensions site, so I have the latest version of it now.
At the time I just launch GNOME Wayland, the weather data is missing. In this case, even if I click on the "Refresh data" button dozens of times, as a result, absolutely nothing happens, the weather data does not appear. Then, when I already stop trying to click on the "Refresh data" button and switch to doing my other things, after a few time passes, about one hour, then the weather data appears on its own. But after restarting my operating system, I again do not see the weather data for about an hour, but sometimes the weather data may appear on its own after about 10 or 20 minutes. Just in case, I will say that I have set in the settings to update the weather data every 10 minutes.
On X11 there are no such problems, this only happens on Wayland, but on X11 the weather data is always immediately visible right at the moment GNOME is launched.
If you need any additional data for diagnostics and debug, such as, for example, logs, etc., then feel free to ask me to provide them. Thank you.
