Sudoku Tricks: Sometimes What's MISSING From The Grid Is Key

Today Simon attempts another puzzle from Richard Stolk's Sudoku Variants Series: Confetti Sums Sudoku - the inspiration for which Richard credits to Stephane Bura. You can play the puzzle here:
https://cracking-the-cryptic.web.app/sudoku/3FN9p4Hm83

Rules: Normal sudoku rules apply. In all cases where the sum of two horizontally or vertically neighbouring digits is A, B or C, a white, grey or black circle is given. A, B and C are different and finding their values is part of the puzzle.

If you are NOT a patron of the channel on Patreon and would like to get a taster of the hunt then you can download the preamble (which consists of two letters: one from Angus MacGuffin and one from ______; together with the notes about the puzzles which seem to have been written by a very unpleasant character indeed) and try the first puzzle at the link below.
