I've been attempting a skip in the daycare where you jump out of the area after getting the security badge and skip the 12:55 trigger by jumping on a palm tree, but i cant get the last part to work which is jumping over a gate by doing a glitch similar to curtain climb. is there a better way to skip this part besides not doing it at all?

I can’t do the fizzy faz skip for the life of me. any tips or things I could be doing wrong? (I’m on ps5)

I've been practicing the ps5 Vanny ending run but am unsure of when timing starts is it once you skip the opening cutscene or some time after that?
