Community, I want to share with you my experience.
Exactly like all of you I was permanently banned due to cheating reason that of course were not true.
Did many appeals nothing happened, they confirmed me the ban and there was nothing I could do about it.
I was pretty desperate at this point and I was thinking of writing a letter directly to Respawn even though I don't think it's even possible.
This morning I tried one last stupid thing that i never tried after the ban.
I used to play Apex via Steam, but thing morning I logged and decided to play through Origin, and guess what?
I could play normally!!! This is just incredible.
I don't know if they lifted the ban yesterday without any notification or the switch between Steam and Origin actually made it work.
Only thing I know is that before yday If I tried to play I was getting kicked out of the lobby just before the pick a Legend Menu with the error code:
the client's account has been banned: Banned (or something like that) and the code snake error after that.
Give it a try guys, maybe this actually works for you aswell.
I'm to scared to go and try to play through Steam again that maybe I get the ban again and I'm all stuck all over, so I will stick to Origin for now.
Hope it helps!
