Do all questions have to or need to be answered?
Of course not.
My whole problem with Poe’s escape is that the movie tries to provide a single, pedestrian explanation for events when it should remain open to imaginative embellishment. It implies that Poe was unconscious for the rescue of BB-8, then found a way back to the Resistance in time to save the day at Maz’s Castle. It’s fine from his point of view, but it’s not particularly interesting and makes the First Order look like a bunch of incompetents for not finding him.
To make the scene happen at dawn it would allow for more interpretations, including many acts of derring-do which cast himself and the First Order in a far more impressive light. The film can suggest, but it’s a very Star Wars thing for the viewer to build the action in their imagination.
