Disconnected: Detected Data Mismatch

[DiplomatDota]

I haven't played in almost a year. Reinstalled the game, linked my EA account back to steam (had to do that again for some reason), and then got in. Things looked fine, I opened the shooting range, did some stuff there, then left. After that, I noticed that my level was 1, I couldn't access legends or skins, and the values for all of my currencies looked underflowed (i.e. -9999 crafting metals). I restarted the game, but upon getting to the main screen, was unable to connect to the game servers with the subject line error.

Changing data center did not fix it. Reinstalling the game did not fix, verifying cache did not fix, and restarting the PC did not fix.

I also recently redownloaded the game but I didnt even get past the Main screen. And my profile has multiple heirlooms and 150 shards. Not to mention Stats that are #1 in the world on certain leaderboards.

Same error after unliking my steam account by accident contacted ea help and they basicly told me I'm screwed, I know ea is a big company but it makes you feel awful when you spend thousands of dollars and thousands of hours playing a game to be told your screwed.

Same here, I have tried everything but it did not work out.. hopefully they gonna fix it but i think they wont bother...
(I have tried it with another account and it worked but starting a new account after more than 1000 hours, skins heirlooms.. is not gonna happen.)

Same here, I can't get past the main screen because of this error.

I also haven't played Apex for about a year.
Logging in with another account does work for me, too. (of course I don't want to do that though)

Other things I have tried without any success:

• Removed the "Saved Games\Respawn\Apex" folder
• Used the EasyAntiCheat repair tool (Apex\EasyAntiCheat\EasyAntiCheat_Setup.exe)
• Reinstalled the game both on Steam and in the EA app
• Updated Windows and the Nvidia GPU driver.

It Is not a problem of our PC, internet or whatsoever. 

I gave my log in to a friend of mine and he also did not manage to connect from his PC (in another country) giving him the exact same error.

So it's a problem of our accounts saving cloud data i guess. only they can fix this.
