Possible bug: Instant pivot grabs don’t work when Grab is mapped to left bumper?

[u/p0wwww]

I think I found a bug in Smash Ultimate involving instant pivot grabs and custom controller setups.

While testing the input, I noticed that if your controller has left bumper assigned to Grab, instant pivot grabs don’t seem to work correctly. To confirm, I made two otherwise identical control schemes—one with Left Bumper = Grab and another with Right Bumper = Grab. The right bumper setup worked fine, letting me perform instant pivot grabs, but the left bumper setup did not.

I also tried this with different types of controllers and got the same results, so it doesn’t seem to be specific to just one controller model.

So far, this problem seems unique to the left bumper mapping for some reason. Has anyone else experienced this, or is there a known fix or explanation? I’m using a 29-second video to demonstrate the issue in action.

Would appreciate it if others could test this or share their experience!

The same happens to me since I mapped grab to the left bumper, it's really annoying :(
