I’ve been dealing with the exact same thing it doesn’t even tell me how long it’ll be banned? Then tells me to lift to the restriction to purchase a premium pass or something like that. I even checked with the bot here and I have no reports or offenses. I just want to play I was able to yesterday, but not the day before for the same reason.
Unfortunately due to abuse from free accounts, IPs now get restricted when they abuse their accounts for a short time. The only quick resolution is as the game suggests; purchase Premium. Otherwise you can wait for the restriction to lift itself.
