What happens if our match is unfinished in terms of the scores submitted?

You can submit an unfinished match score in the Nettla app, and it will show in your history, but the algorithm is not able to calculate level updates based on unfinished results. If you and your opponents want to make sure an unfinished match still counts, you will need to agree on a ”fictional” score that represents a full match score and report that score instead.
