I have this behaviour 100% of the time I don't fly manual landing. Exactly the same as the video quoted:
Normally I would fly manual but I was just landing into Dubai with limited visibility so left it on autoland. At around 500ft the plane starting oscillating up and down (attack angle would go from 1% to 7% and back again) with massively varying throttle.
Checked all the inputs and this was fine. I can replicate this 100% of the time at any airport (confirmed it happens at Manchester, Heathrow, Hong Kong). However it did not happen until about 3 weeks ago, and the initial build would land flawlessly.
Happens on 900 & 1000. I've not tested 900ULR yet.
edit: just realised this is the 2024 forum. This is happening on 2020 as well.
