DISCONNECTED: steam ID mismatch.

 Same here

Same problem here!

EA please fix this error.

OK guys after a long research I found something that might help us. 

But I should say it can be temporary so we still have to wait for @EA and @RESPAWN to fix this issue. 

1.  Make sure the game is closed. 
2. OK so you can download GEAR UP or EZ CONNECT application on your device and test the EU servers ( like Germany or Netherlands and etc. ) 
3. after that run the game and you should be able to play. 

Thanks for your support. 

It would be great if you let us know about the updates here in this discussion. 

I have same problem. If you find solution let us know...

Same here , Wanted to try unlinking and relinking steam but changed my mind after reading the list of possible complications .

Pls share any possible solutions 

tho i doubt this one would be user fixable 

Hey everyone,

Just wanted to confirm that we are aware of this error popping up recently alongside some other disconnection and crashing issues.

This has been passed along to be checked into further, thank you for the reports!

can i have your exitlag setting?

After logging in apex on steam , it show : steam id mismatch .
What should i do ?

i have the same issue i think the problem is the iran ip for this game when using vpn or exitlag not showing me this error but still have it sometimes
