Are you specifically referring to the mobile client of Element? i wasn’t away of anything with the desktop client that has anything to do with location.

Some instances have their own political leanings that can affect content and moderation. The “Tankies” referred to in the previous post tend to be Russia/China supportive anti-capitalist posters. Not everyone on those instances leans that way (I don’t), but some instances don’t federate with those three, especially lemmygrad and hexbears, because of it. You can also individually block instances if you personally don’t want to see their stuff. On the whole, you probably don’t need to worry about it, but if it becomes annoying you have the option.
