Can't accept rematch

Why on earth would the developer of the Android app not add a clickable button for rematch requests after leaving a game page. It's the dumbest decision ever. Now whenever I come out of a game, and the opponent wants to play again, there's no way to accept it.

Perhaps the bigger the question is
" How does a giraffe have an android phone?"

I guess it depends. Do you mean the old, unsupported one that was built as someone's personal hobby; or the new, definitely still incomplete one?

I play on my my iPad so when the rematch is bouncing I just click it
