Hi, please check version 11.3, this should fix the slowdown issue. For the "ignore axis" issue - it depends if you're trying to use the DPad. These register as an axis, not buttons (for some reason), so they'll get ignored.
check out this video we made (which youtube has decided is a short)
our issue is the checkbox prevents an axis from being bound when its on, but if we want to bind a button we still have to go through the process to center out a bunch of axis even with the box ticked, essentially with the box ticked and an axis is being detected it will block all binding completely (we checked and this behavior works the same when you hold an axis maxed while trying to bind a button on a standard controller) also we really really appreciate you going through the effort to set this up since we know its a pretty edgy edge case just in case we come off as entitled!!!!
