    Can you solve this once more and confirm that no given digits or lines are missed ?
    This feels way too hard

    This has been tested and confirmed unique and solvable. Some steps are pretty tricky indeed.

    1. Box 1 has a 2/3 pair which interacts with one cell in box 2 with 2/3 as candidates. One of the options can be eliminated.
    2. Later in the solve, you can see that the whisper in box 5 has some restrictions. One of the ends of the whisper must have digits 6/1 or 4/9. Consider the position of digit 3 in both scenarios. It implies some key elimination in box 4, after which all should flow nicely.

    I solved it on video on my YouTube channel but with French commentary.
