Thibault and the LiChess Developers also gave us Zen mode. (As in: No distractions.)
That said ... there is NO OBLIGATION to respond to a takeback request. The game does not stop. If some idiot doesn't want to move because s/he didn't get an affirmative response to a takeback request, then, let the idiot time-out. And then let the idiot come and complain here, and then let the idiot be skewered.
You may not like my tact, but, the OP's behavior is as equally obtuse in coming to an Internet forum to whine and complain about lack of basic comprehension; that of seeking sympathy for one's own stupidity. I can't help or fix that. (I find the OP's behavior offensive. First let a game time-out, then come and complain about it. No reason to treat anyone other than they way they show and expect treatment from others.)
