Hi ! I got some issues, the first one when I open the app it under my name it appears " Roménia" and I'm from Portugal. And I can't collect the diamonds from the some achievements. And there's no option to change, please fix this.
You can change country if you login through website, go to profile, edit profile and change it there.
The achievement thing is a known issue and we collect them all in one central topic, so you can report it there: https://forum.onlinesoccermanager.com/topic/9049/achievements-bug/29
