And the only region for whom the explore tab is working is America as nothing is localized.
Explore tab is sorted by language, not by region, so it works too for any sufficiently large foreign language country (Spain/Latin America, Portugal/Brazil, Italy, France, Germany, Sweden, Poland, Czechia, Russia, China, South Korea, Japan).
I wish Mastodon implemented Akkoma-style bubbles of related instances, which would allow to create, like, Explore tab but only from (manually selected) several Australian instances.
