Nope, patch didn't change anything. Also tried playing with controller bindings in SteamVR settings. Seems like the problem is not in bindings. - as hands seem to react correctly to Trigger and Grab buttons
Oh that's really lame. Not surprising though as the patch was bindings for Vive and Oculus specifically. I really don't know how to support WMR devices with SteamVR. Thanks for trying the patch and thanks for the suggestion to make a video!
