The app times you out for 3 hours due to poor internet (even in Rapid). The moderators will send threatening messages, asking you to complete games once started, else you get a temporary ban. In case, you are in the endgame and the WiFi is kinda down for a moment, the opponent wins and you receive a ban. You don't have a reply feature, the moderators/ lichess are not even ready to listen to a user's issue. Useless moderators, they time you out for internet issues.
