Does the Designated Survivor series have a closed ending?

The series can be seen longer on Netflix. I would be interested to know whether the series will have a completed ending after the third season despite being canceled.

No, unfortunately not. Annoyed me. I liked the show itself, but it was probably too unrealistic that an American president could have something like self-doubt and altruism. Or that after a - not necessarily self-inflicted - misstep, he might consider resigning. Ridiculous in the face of reality.

Too bad, I had considered watching the series again because I had started it on short notice a few years ago. But if it doesn't have a finished ending, it would all be in vain: / That already got me so excited with Colony when they stopped from one day to the next and the story was never told to the end. : /
