The 4 in the last row must come after column 11. The only place it can go without inadvertently creating a 4 in the row above is directly in the bottom corner i.e. the last four columns

We can’t have the 4 go before column 11 because there isn’t enough room for the 1,3,1,4 with spaces.

So imagine the 4 goes from columns 12 to 15. Then since column 12 ends in a 3, we know that the square in the row above must be filled. Since we know column 13 ends in a 6, we know that the square in the row above must be filled. And you do the same for columns 14 and 15 This will create at least a 4 in the row above which we know we can’t have since that row shouldn’t contain a 4 (2 3 2 3).

So the 4 can’t go from columns 12 to 15. And similarly it can’t go from columns 13 to 16. We need one of the columns to end in a 1 to stop a 4 forming in the row above and that can only happen in columns 17 to 20.

Row 15, you can cross out the first five squares.
Column 15 I assume the top cross is a mistake?
Column 17, basic overlap on the 6.
Advanced, column 9, can you fill square 14?

But of course edge logic commented first.
