I'm a bit stuck on Puzzle 29. I've made it up to the point of the final hint, but said final hint seems to make no sense. It mentions placing 7 in r8c5, then 9 in r2c5. The hint says this somehow forces 8 into r8c8. I have no idea how this would happen, regardless of the fact that 8 cannot go here since it's a length-3 arrow. Could someone help me from this point? (Attached is where I am in the puzzle, along with the hint. Smart hint cannot generate any hints.) https://gtm.you1.cn/sharedfiles/filed...

The hint says that R7C5 cannot be 1/9 as the row clue is too big. But the row clue is 21, that can be 3 digits, and allow the 1/9 digit.

I think it's time we talk about having access to more color options than the default 3. Most of us that continue to follow the daily puzzles from Simon and Mark find the necessity of using colors effectively to track the options for squares, and while the use of colors has been fine with other apps, it's beginning to show its inadequacy for more difficult variations....

I'm at this point in my puzzle (see screenshot) and I don't see why r2c3 cannot be 5. https://gtm.you1.cn/sharedfiles/filedetails/?id=2504841861 If I try to make it a 1/3/5 on the left it doesn't seem to break anything: https://gtm.you1.cn/sharedfiles/filedetails/?id=2504837796...
