GPS Signal Lost

A Scojo Setting Saturday prompt submission for turning normal outside clues into diagonal ones. Thanks to bootenks and gdc for testing and feedback.
Rules:
- Normal sudoku rules apply.
- Skyscrapers: Clues outside the grid indicate how many digits are 'seen' looking into the grid along the indicated diagonal. Digits are visible when they are larger than all digits before them.
- Grid borders extend the sight line of the clues at a 90° angle, and can be extended multiple times, For example the 3 clue above r1c4 sees along the indicated diagonal from r1c3 to r3c1, then continues along a new diagonal from r3c1 to r9c7, a third diagonal from r9c7 to r7c9, and finally the fourth diagonal from r7c9 to r1c3.
Below is an example of how a skyscraper clue would work. The seen digits from the clues perspective are the circled 3, 4 and 5
All feedback (positive or critical) appreciated!
Solution code: Row 3, left to right (9 digits)

Sensational! Overwhelming at first glance but when one starts to piece together what's going on with the grid, the dread turns to delight and you are left with a smooth ride.

Very nice variant that felt very different from solving a normal skyscraper puzzle. Not hard if you draw your coloured lines and ask the right questions. Thank you for setting all these great puzzles!
