Option to Forfeit

Whenever I am playing FC Mobile and I’m up by 2+ goals,  my opponent just closes the game and I’m stuck with the A.I for the rest of the match which is annoying and not fun. I know some people do get disconnected due to internet issues but there should be a 30 second timer to be able to rejoin the game otherwise it will be a forfeit or the opponent can manually press the option to forfeit.
