I support this feature request. In the meantime, as a workaround you can rename your year folders as follows: "0 2021", "1 2020", "2 2019", etc. and they will sort as desired. If you're using "Organize by Date" in the Destination panel in Import, highlight the year folder that's appropriate (rather than your master photos folder), and choose a date format that does not include a year folder (e.g. "2021-01-20") - or leave it as before, and after Import drag your shoot folders into your renamed year folder.
Thanks for merging me in. I search for previous posts, but couldn't find this thread amid all the threads talking about sorting photos in the grid display.
So many years of an obvious need to view the most recent work first but Lightroom laughs and ignores you and still you spend your money on the product and wonder why Lightroom does not give a dam lol, cancel and tell them why then they might listen - but you will not and for the next 5 years and beyond we will still see the same issues and the sam indifference from Adobe, so nobody to blame other than those that pay a company for ignoring them ! The actual forum is hosted by Adobe and they simply ignore and you continue to buy and wonder why you are ignored. lol
