The nudging button is inconsistent. I want to be done with a game and I cannot nudge--the little hand does not appear consistently--it does for some games; not for others. I hope EA can address this--it is annoying.
When I called about this they said that the opponent had to look at the game before it got nudged. One trick I've been using is to post an emoji in Chat. That way the person stops and looks at it.
