Horizon Forbidden West - Diving Head First from Sunwing

Описание: TL;DR: This can only be done with the PS4 version of the game.

Setup (PS4) / Initialization. People have stumbled into this. This is the method I found that reliably allows this to happen:
1. Climb. Hold Cross-button and pull left-joystick back and climb to an altitude equivalent to the bird flapping its wings 20 times.    • Setup  
2. Dismount into water. Tap Square-button. She will go in feet first.
3. Repeat climb and dismount a second time (1 and 2).
Diving steps:
1. Climb to some altitude.
2. Hold Square-button for at least couple seconds then,
3. release Square-button then quickly hold Circle-button while simultaneously pulling left-joystick in the direction of dive.
Notes:
Tested on PS4 version 1.00 from installation discs with no updates. Tested again with update 1.18 and it still works.
I have not been able to get the PS5 version to dive, even without the Burning Shores DLC. The PS4 version allows it on the PS5 though. The DLC is not available for the PS4. This does not work on the PC version either which is the Complete version.
Dives may stop working once there is a failed dive (she just falls feet first in the water, possibly due to missed timing). To fix redo Setup.
Save before doing. Sometimes the camera does not reset and is stuck magnified and the fix is to reload a Save. This problem can be forced by activating the Shieldwing during a dive.

Pathology: I could not get this to work when I first saw this. She just falls feet first in the water. I've seen a number of videos but I was not able to make the dive happen from the instructions. I bought the game digitally for my PS5 before the Burning Shores DLC was released. Since then I've received updates and the DLC. Then it occurred to me the videos showing this feature were 3 years old. I also saw in the comments most people were not able to do this. Some comments say it may have been patched out. Then I bought the disc version for the PS4 and PS5. Installed them without the internet to prevent updates. After spending 5 days and 30 hours of playtime to progress to the point to get the Sunwing on my PS4 Pro is when I tried various combinations to make this happen. Then it happened accidentally. It took awhile to get it to happen again. After I found the recipe I moved on to the PS5. First I deleted the DLC and left the digital version alone. It still would not allow me to do the dive. Then I installed the PS5 discs and transferred my PS4 progress to the PS5. The PS5 saw the disc version as a separate game. The PS5 disc set is the Complete version which includes the Burning Shores DLC. The PS5 version of the game does not allowed this. Then I installed the game on my PS4 Slim and transferred the progress and allowed it to accept updates which was 1.18. Somewhere to this update resetting of the Skill tree was made. The dive works with 1.18. Then I installed the PS4 version on the PS5. That works.
