Apologies if I am unable to relay my personal experience to this issue correctly/accurately, but since this is relevant to the creative input actions option being absent in the settings, it seems appropriate to provide my input in this thread.
Platform: Playstation 5
Input Device: Dualsense Controller
Island Code: 7154-1898-4800 (Lumberjack Heroes created by itsjacky)
The Island contains a randomly spawned, menu-based mini game (Flower Bloom) where the player must press several correct sequences of directional buttons within a limited period of time.
Because the input commands that appear in the game UI are strictly cardinal, there is a very high chance that sensitive movement of directional analog sticks will create the wrong direction, thereby disrupting the game’s progress.
In recognition of this issue, the minigame had provided a visual solution for controller users by instructing them to customize the inputs via the Creative Input Actions menu within the settings. This function was present in previous versions of Fortnite, and I was able to use customized inputs to progress through the minigame.
However, now that the Creative Input Actions menu is gone as of the current Fortnite patch, I am currently unable to play the minigame as intended on a controller device.
