The web store is not working

Hey there! Could you please confirm which region you’re playing from? Minimum age requirements can vary by country. Also, try logging out and signing back in to help sync your account. If the issue continues, scroll to the bottom of the webstore page and use the Customer Support / Contact Us option to reach the team directly.

I am in the UAE so middle east I think 

Also I can't redeem codes

I used the new redeem code ITSTHETOTYS and it said 'invalid captcha'

On your account, do you see options to link your FC profile to any of the available services (Facebook, EA Account, etc.)?
If those options aren’t visible, there’s a chance the account was created with an incorrect date of birth (which can limit certain features).
