I've seen this in MSFS2024 too.

Can you provide a video where the autoland is not performing properly? I used your "steps to reproduce," but the autoland worked fine. The flare mode engaged at approximately 40 feet RA, reduced the rate of descent as intended and provided a nice, firm, but not hard, touchdown.

Seems to be consistent for me on ENGM19L: https://youtu.be/2hHevix41gs
Development version 3c71f5d (current as of this morning).
I'll try some other airports and approaches when I get some time.
It was working fine for me; I don't use autoland enough to know exactly what broke and when.

Note that the tailwind for your landing (15 knots) exceeds the autoland tailwind limit of 10 knots. Here's one that's just within the 10 knot limitation: https://1drv.ms/v/s!Ajsy7Ey4_8uFgZ1fXaHMcqdTWDn6Jw?e=0GZPAl. While still firm, the rate of descent has been reduced to about 300 fpm at touchdown. Feel free to submit more examples for us to look at.

This happened at SKCL in my country. (It’s the same at all airports.) For some reason, the speed didn't reduce automatically during this flight and stayed locked at 250 knots. I manually set it to the limit, but the same thing happens even when the speed does reduce automatically. The flare doesn’t seem to engage, resulting in a 494 fpm landing. https://drive.google.com/file/d/1VvG65Wlenz9CcuqV3X3OG4OF1jK04psp/view?usp=drive_link . In the stable version, it’s around 150-250 fpm, and you can notice when the aircraft slightly raises its nose. When switching from LAND to FLARE, the nose usually rises slightly, making the landing much smoother. In this version, it does not. Sorry for my translated English.

Here's ENGM19L again, with no wind at all. No flare - in fact, if anything there might be a tiny nose down input after FLARE engages: https://youtu.be/lu7zw87cyJA
Probably unrelated, but I also noticed that it calls "200" instead of "minimums" - I thought the latter was supposed to be prioritised.

Thanks for the additional inputs. I think @Leonardop448 is on to something here. There seems to have been a change between the stable and dev versions that made the autolands worse. I tried ENGM 19L with the stable version, and the flare was much better. I'll bring this to the team's attention and see what can be done.
