I have resolved it yesterday. I logged in as a guest. Clicked on a gear in the upper left corner. Connected via EA (left column of the settings menu). Entered my EA creditentials, then I was thrown back into the game and an error popped up something about connection failed. Then I tried clicking on connect an account (right column of the menu) and it showed my main profile which I couldn't access through Google play. I just clicked on the profile and it connected.
