German Sums 3 (Sandwich Edition)

I am happy to share with you another episode of German Sums constraint :-)
Tester's estimated difficulty 1.5*
I hope you will enjoy and I would be really grateful for all the comments and ratings.

Normal sudoku rules apply.

All clues are both Sandwich and German Sums.

German Sums: A clue outside the grid gives the sum of all adjacent digits with a difference of at least 5 up to (and not including) the first digit with a difference of 4 or less in that row or column from the direction of the clue. A digit in the first cell is always included in the sum.

For example, if row 4 is 728315469, then the sum would be 20 (7+2+8+3) from the left side and 9 from the right side.

Sandwich: A clue outside the grid gives the sum of the digits appearing between the 1 and the 9 in that row/column.
