Camera animation not working in 5.1.1

[SoulicPhoenix]

I watched/followed Unreal Futures. I’ve been happy until the last tutorial. Around from 6:10 in the video below, the camera animation doesn’t work. Although I create the key frames in the transform, it literally doesn’t work.

Recreating a Scene From Super Giant Robot Brothers | Unreal Futures: Careers in Animation | Part 5

So, I’m wondering if it’s changed in 5.1.1.
Another issue is that the angle of every scene looks different from my expectation. I guess they are fit to the last scene, MyShot-3, because MyShot_3 looks fine.
I guess so many things have changed in 5.1.1.
