Great game until 1 month ago! Now at the loading screen, I receive a message continually that says : ATTENTION login failed [neon error code: 600]. Very frustrating!I have accomplished a lot of tasks in the game; now it's just stuck. I have rebooted,powered down,removed, and re-installed app, and the same problem continues to occur. Samsung Galaxy Note 20 ultra is my platform. Ughhhhhh
