I cannot view many (most?) posts on Lemmy.world while I’m logged into my account. Logging out makes them visible. Issue persists across browsers (FF and chrome).
My best guess is that I’ve somehow messed with the allowed languages setting? But I don’t see how to ‘reselect’ Undetermined in languages, or otherwise reset the settings.
See if you have deselected ‘Show read posts’ in your settings
Issue persists after toggling this setting off and on again (and during every step in between).
