it doesn't cut

Equal to "it doesn't matter". You can meet this expression in different songs.

We all have gathered in his chamber in order to support him during his sickness, but seems like it doesn't cut. He still can't notice anyone in his room. He thinks he's alone for the whole rest of his life.

sorry doesn't cut it

It means apologizing isn't good enough for anything in order to fix the situation

Yeah, well, sorry doesn't cut it through this time.
