Just wanted to comment that am on Version 2.28.0 on android and I don't have this issue.
Only thing that comes to mind is that last time I saw someone have similar issue was because they had accidentally deselected "english" or "undetermined" language settings in their profile on lemmy's default web UI.
Might want to try checking those settings out, don't remember how the other person had accidentally deselected languages but they were just as surprised.
