Where did you download it? From what Ive heard the Play Store version lags behind a bit. I got it via f-droid and now have buttons to jump between top level comments (this isnt the only change but it is the most obvious on first glance). A lot of instances arent on the newest version of lemmy yet though, since the sign up captchas were temporarily removed and preventing bots to sign up is way harder without it. I dont know if there will be software conflicts due to this mismatch though.
In many places the cities were retrofitted for car centric infrastructure already, why couldnt it happen again?
