That did the trick. I had a logical error in my original solution with one of the white dots, but Sudokupad still said the final solution was correct. Appreciate the update! Nice puzzle.

Very nice! The length 4 line spanning box 2 and 3 doesn't seem to be necessary for the solve, nor does the length 4 line spanning boxes 6 and 9. (I did not need to use them)
Great puzzle, thanks for setting!
