Pings to US central and some US west servers are very high and fluctuating for me currently. My ping to US west is usually close to 80 and ping to US central 40-50. I Joined a Chicago server with 150-200 ping and had yellow and red connection indicators the entire match. A large number of players in the server also had 150-200+ ping so I feel like something might be off at the moment.
Also I get "unknown error" when loading the game multiple times and am still able to open the game but my account shows no level despite player stats being correct. Usually the second time I open the game it signs in fully but it still usually takes two tries to exit.
