When I play in offline mode and achieve a high score, it doesn’t get recognized when I close my game than open it again while connected to the internet, I can tell because it’s either one of two things that will happen: [1. The score in the ranking page is lower/older data comparing to the one showed in the main menu.] [2. The ranking page shows only the score, but not the ranking or top percentile.] Also if this happens for daily challenge, it will also not be recognized once you return online. I only discovered this because I went to china and was on and off from using VPN, which seems to be needed to connect to mini metro servers.
