I’m with you on this, I just did some research and found the latest update came with a massive ban wave. Also it has been noted that if you were unaware of the game update on a jail broken device and launched the game it would auto close and kick you out. This flags you to Nintendo under the anti cheat as the bypass is obsolete due to the update. This is also causing the ban wave.
way around it if you choose to return, open the game on a non jailbroken device first to ensure if an update is there or not, ensure the game updates before launching it on your jailbroken device.
im close regardless to deleting the game myself, the last pipe with winter peach or whatever was a pay wall and the only way to win in ranked is if you had all three items in the spotlight. They are shifty. I’m done with it.
